Use the uploaded character image as the PRIMARY and STRICT character reference. Create a polished modern Japanese anime character illustration designed as a premium circular profile icon. The uploaded character must remain recognizable and must be dynamically adapted from the reference image. Do NOT replace the character with a generic anime character. Preserve the character's core visual identity: * hairstyle and hair silhouette * hair length * bangs and fringe shape * hair texture * dominant and secondary hair colors * eye color * eye shape and eye style * facial structure * skin tone * facial expression and overall personality * outfit design * neckline and collar * sleeves * shoulder details * ribbons, ties, belts and straps * armor or clothing details * jewelry and accessories * decorative elements * signature props or weapons when they are part of the character's identity The final illustration should feel like the SAME character reimagined as a polished premium anime profile icon. STYLE: Modern high-end Japanese anime illustration with a refined Korean game-community profile icon aesthetic. Use: * clean, elegant anime line art * polished digital illustration * refined cel shading combined with soft gradient rendering * smooth skin rendering * subtle soft blush * glossy anime eyes * detailed but controlled hair rendering * layered hair strands with soft highlights * carefully rendered clothing folds * polished metallic and leather materials when present * subtle specular highlights * crisp edges * sophisticated lighting * delicate facial features * large expressive anime eyes, while preserving the original character's eye shape * elegant mature anime facial proportions * slightly stylized proportions * high visual polish * premium game character illustration quality The result should NOT look like a manga panel, comic page, sketch, watercolor painting, or photorealistic portrait. Avoid visible screentone patterns. Avoid rough manga hatching. Avoid excessive line-art texture. Avoid flat generic cel shading. The rendering should be detailed, smooth, clean, luminous, and polished. CHARACTER PROPORTIONS: Use mature anime character proportions rather than exaggerated chibi proportions. The character may have a slightly enlarged head and slightly stylized proportions for profile-icon appeal, but should still look like a mature anime character. Do NOT use a super-deformed chibi body. Do NOT use a childlike appearance. The face should be elegant and attractive while preserving the original character's identity. COMPOSITION: Create a close-up upper-body bust portrait. Show: * entire head * entire hairstyle * face * neck * shoulders * upper torso * upper chest * important outfit details * important accessories * character-defining props when appropriate The face should be the primary focal point, while the outfit and accessories remain sufficiently visible to identify the character. Do NOT create a full-body composition. Do NOT show legs or feet. Do NOT zoom in so aggressively that the hair, head, shoulders, or important accessories are cropped. The composition should resemble a premium anime game profile icon. CIRCULAR PROFILE ICON: Place one large soft pastel circular background behind the character. Use a clean white outer background. The character must remain completely inside the circular background. The circle should function as a clean profile-icon badge. The character should occupy most of the circle while maintaining a comfortable but relatively narrow safe margin. Keep approximately 5–10% visual breathing room between the character's outer silhouette and the circular edge whenever possible. Do not make the character excessively small inside the circle. The circle must remain clearly visible around the character. The character's head, hair, shoulders, hands, accessories, props, and outline must remain inside the circle. Nothing important should extend outside the circular boundary. Do not crop the top of the head. Do not crop the main hairstyle. Do not allow the character to touch the edge of the circle. POSE: Use a natural, elegant upper-body pose that suits the character. The pose should be dynamically selected based on the uploaded character's personality, outfit, accessories, and visual theme. Possible pose ideas include: * hand near the face * resting cheek on one hand * holding an accessory * holding a fan * holding a signature prop * relaxed hand near the chest * slightly tilted head * subtle side glance * looking toward the viewer * looking slightly away * relaxed shoulders * elegant three-quarter pose * subtle confident pose * soft casual pose Do not force the same pose onto every character. The pose must feel natural for the specific uploaded character. EXPRESSION: The facial expression should be dynamically derived from the uploaded character. Preserve the character's established personality and emotional atmosphere. Possible expressions include: * calm * elegant * cool * confident * slightly smug * shy * playful * relaxed * sleepy * soft smile * teasing * serious * emotionally tired * expressionless Do NOT automatically give every character the same smile. Do NOT automatically give every character the same eyes or facial expression. The expression should complement the character's design and personality. HAIR: Hair is one of the most important visual features. Carefully preserve: * original hairstyle * hair silhouette * hair length * bangs * parting * curls or straightness * volume * distinctive strands * original hair color * secondary hair colors * subtle highlights Render the hair with many clean, controlled anime strands and soft luminous highlights. Avoid overly simplified hair. Avoid changing the character's hairstyle into a generic anime hairstyle. EYES AND FACE: Preserve the character's original eye color and overall eye design. Use polished anime eyes with: * clear iris structure * subtle gradients * glossy highlights * refined eyelashes * delicate lower eyelid details Keep the facial structure elegant and mature. Use a small, delicate anime nose and softly defined lips. Do not exaggerate the face into a generic kawaii chibi face. OUTFIT AND ACCESSORIES: Preserve the original outfit as much as possible. The upper-body clothing should remain recognizable. Important details such as: * collars * ribbons * ties * armor * shoulder pieces * chains * jewelry * belts * decorative patterns * gloves * sleeves * flowers * fans * weapons * signature accessories should be retained whenever visible in the reference. Do not simplify away the character's signature costume elements. If the reference character has a distinctive weapon or prop, it may be included as part of the portrait. However, keep the prop compact and fully contained inside the circular frame. Do not let oversized weapons dominate the composition. BACKGROUND: Use a clean white outer background. Inside the white background, create one large circular pastel backdrop. The circular backdrop color must be dynamically derived from the uploaded character's visual palette. Consider: * hair color * eye color * outfit colors * accessory colors * accent colors * character personality * overall atmosphere Use harmonious pastel versions of the character's existing palette. The background should complement the character rather than overpower the character. Lavender, dusty purple, muted blue, soft pink, pale violet, muted teal, cream, or other harmonious pastel tones may be used when appropriate. Do NOT force the same background color onto every character. DOODLES AND DECORATION: Add subtle decorative doodles inside the circular background. Possible elements: * tiny stars * sparkles * dots * small flowers * petals * geometric shapes * tiny clouds * subtle scribbles * butterflies * small decorative symbols * delicate line-art motifs The decorations should visually relate to the character's theme and color palette. Keep the decorations sparse, elegant, and secondary to the character. All decorations must remain inside the circle. Do not create a busy background. Do not use a magic circle. Do not use a halo. Do not add unrelated fantasy symbols. LIGHTING AND COLOR: Use a soft, polished anime lighting setup. Create: * gentle facial highlights * soft hair highlights * subtle blush * controlled shadows * refined material highlights * dimensional clothing shading Use a cohesive limited color palette based on the original character. Keep the overall image soft, elegant, clean, and harmonious. The final colors should feel polished and slightly pastel without washing out the character. LINE ART: Use clean, confident anime line art. Lines should be: * smooth * crisp * elegant * controlled * moderately detailed * slightly varied in thickness Use stronger contours around the character silhouette and finer lines for hair, facial details, and costume details. Do not use rough sketch lines. Do not use messy crosshatching. Do not use comic screentone. FINAL VISUAL TARGET: The final result should look like a premium modern anime character profile icon commonly seen in: * Korean game communities * Discord * KakaoTalk * SNS profiles * anime game communities * modern character illustration collections Think: "high-quality anime game character portrait + elegant Korean profile icon + pastel circular badge + detailed character rendering" The image should feel polished enough to look like an official character illustration rather than a simple avatar. IMPORTANT CHARACTER ADAPTATION: Every uploaded character must produce a different result. Dynamically adapt: * pose * expression * background color * decorative motifs * lighting mood * composition balance according to the uploaded character. Do NOT reuse the exact same pose.
