GPT Image 2.0 Prompt - Selfie sereno ante el espejo del gimnasio

Create an authentic 3:4 vertical smartphone mirror selfie inside a modern gym, fitness studio, or changing-area interior with multi-panel mirrors. An adult woman in her 20s stands slightly left of center in the lower-middle portion of the frame, seen from a three-quarter rear-side angle rather than facing the viewer directly. Her hips sit close to the visual center while her ribcage rotates slightly toward the phone. She lowers her head and looks down through oversized transparent, faintly amber-toned glasses toward the phone screen. Her lips are naturally slightly parted, and her expression feels quiet, restrained, focused and self-assured rather than posed or smiling for the camera. She has extremely long dark-brown hair, nearly black, reaching the hip area or slightly below. The upper portion is loosely pinned or half-up with a little natural volume at the crown, while the rest falls freely down her back. Keep the hair mostly straight but not commercially perfect: include subtle bends, flyaways, mild frizz, uneven strands and restrained shine. Warm overhead illumination should create soft brown highlights across the crown and selected strands. Dress her in a fitted ivory, warm-white or very pale beige-gray athletic mock-neck long-sleeve top made from thin elastic performance fabric. It should hug the body naturally while showing small realistic tension wrinkles around the chest side, waist, elbows and wrists. Pair it with pale cool-gray or softly silver-gray high-waisted fitted athletic leggings with a soft matte to faint satin finish. The leggings should follow the natural waist, hips and legs without looking glossy, latex-like or synthetic-plastic. Her figure should be slender with a believable athletic curve: a relatively narrow waist and more visual volume through the hips and legs, while preserving realistic human anatomy rather than creating an exaggerated hourglass. The chest should only be naturally outlined through the fitted top without adding exposure or artificially increasing volume. Visible skin must remain limited mainly to the side of the face, ear, jaw area, and the hand and fingers holding the phone. The high collar covers most of the neck, while the chest, waist, abdomen, hips, buttocks and legs remain fully covered. Use a light-to-medium warm skin tone with subtle peach-beige and golden undertones under warm indoor light. Keep the skin fine and smooth-looking but realistically textured, visually suggesting clean, soft, naturally dry-satin human skin rather than wax, porcelain or plastic. One hand holds a dark graphite or black triple-camera smartphone around chest-to-shoulder height, while the opposite arm bends behind the waist or rear hip. Add a dark rectangular smartwatch and a small red-brown beaded bracelet on the visible wrist, plus a white wireless earbud or light-colored ear accessory. Her legs stand naturally close together with weight shifted slightly to one side, creating a subtle asymmetric S-curve through the shoulders, waist and hips. It should feel like an instinctive selfie stance rather than a rigid fashion-model pose. The most important compositional feature is the two-level mirror-reflection structure. The main reflection occupies the middle and lower portion of the image and shows the woman from her head to around the upper thighs. A second, more distant reflection of the exact same woman appears across the upper section, revealing more of her rear body, lower legs and white athletic sneakers. A horizontal brass-gold mirror frame, architectural rail or divider runs across the composition and separates these two reflection zones. In the upper reflection, show medium-to-dark gray hard flooring and a noticeable vertical mirror seam. Both reflections must obey physically consistent mirror logic: body direction, phone placement, head angle and accessories must correspond correctly. Never turn the upper reflection into another woman, and never create duplicate limbs, extra hands, legs or fingers. The lower background is dominated by a light-absorbing matte black wall. On the right, place a large orange-yellow geometric brand-like wall graphic with thick black internal shapes and lines, but do not require readable lettering. In the upper mirror area, show the gray gym floor with perhaps one small pale bottle or incidental object far away. Preserve small environmental imperfections such as mirror seams, tiny scuffs, wall marks and floor blemishes. If a social-media screenshot feeling is desired, a tiny white watermark-like shape may remain near the lower-right edge, but do not reproduce any real username, number or readable account information. The photography must feel like a real phone image rather than commercial studio work. Use an approximately 24–28mm full-frame-equivalent smartphone main-camera perspective in a 3:4 vertical crop. The small phone sensor should create relatively deep depth of field, keeping the woman, the black-wall graphic and much of the upper reflected floor fairly sharp. Avoid portrait-mode blur. Mild computational HDR, limited digital sharpening, subtle denoising, JPEG compression and faint digital grain are welcome. Keep the framing slightly imperfect and off-center rather than perfectly symmetrical. Illuminate the scene mainly with warm-white gym ceiling spots and overhead fixtures positioned above and slightly in front of the woman. They create compact highlights on the forehead, nose bridge, cheek, ear, fingers and the ivory fabric, with shadows falling softly downward. The gray flooring contributes a faint cool-gray environmental bounce, while the matte black wall absorbs much of the stray light, allowing the pale clothing and warm skin to separate naturally from the background. Do not add cinematic rim lighting, dramatic backlights or large studio softboxes. The emotional residue should be understated, private and quietly confident, like a personal workout check-in rather than an advertisement. She had just paused during or after training to record herself; she is checking the mirrored composition on her phone now; in the next moment she may lower the phone and continue training or leave. Preserve mirror seams, slight framing errors, incidental reflections, flyaway hairs, natural fabric creases, minor surface marks and digital noise so the result feels like a real social-media fitness mirror selfie instead of a polished campaign photograph. Negative prompt: extra limbs, extra fingers, duplicate person, broken reflection, mirror mismatch, warped hands, warped phone, deformed anatomy, extreme hourglass, tiny waist, added exposed abdomen, added exposed legs, plastic skin, over-smoothed face, latex leggings, studio lighting, strong rim light, cinematic bokeh, heavy blur, perfect symmetry, CGI look, fake silky hair, bad text, readable watermark ID
