Style Type & Characteristics

This SREF style merges the aesthetics of Dark Fantasy, Bio-Horror, and cinematic realism. It evokes the visual language of Guillermo del Toro and H.R. Giger—an artistic expression that perfectly combines organic biological forms with an unsettling atmosphere.

The most distinctive features of this style are its extreme material realism and oppressive tone control. The overall image is dominated by low-saturation cool tones, with extensive use of deep brown, dark green, and gray-black palettes, creating a damp, decayed texture. Lighting is dramatically handled with strong contrasts between light and shadow and soft rim light, making biological forms both clear and mysterious. The depiction of surface textures is exquisitely detailed—you can almost feel the slippery slime, rough shells, and the softness and toughness of biological tissue.

What’s most impressive is its grasp of "beautiful horror". This is not merely about frightening visuals—it injects a strange elegance into disturbing themes, like a flower blooming in darkness. Depth of field control and composition have a strong cinematic narrative feel; every frame looks like a still taken from a sci-fi horror film, full of story tension.

Recommended Application Scenarios

This style is particularly suitable for:

Game Art: Concept design and environment building for horror games, Lovecraftian-themed games, and dark fantasy RPGs—especially for monster design, alien creatures, and atmospheric environmental scenes.

Film and Animation: Concept art and storyboarding for sci-fi horror films and bio-thrillers, perfectly rendering alien life, mutated creatures, or post-apocalyptic settings.

Book Covers and Illustrations: Cover designs for horror novels, dark fantasy literature, and sci-fi thrillers, instantly conveying the atmosphere and tone of the work.

Art Collectibles: Limited edition posters, art books, and visual designs for themed exhibitions, appealing to collectors who appreciate dark aesthetics and surreal themes.

Recommended Prompt Keywords

  • bioluminescent details: Adding bioluminescent elements creates dreamy light contrast within a dark tone, bringing a touch of supernatural beauty to horror while enhancing depth and mystery, making creatures feel more alien or deep-sea in origin.

  • dripping textures: Using dripping textures strengthens the organic and fluid feel of the work, adding a damp, sticky visual experience that makes creatures appear more alive and unpredictable, increasing discomfort in the horror atmosphere.

  • backlit silhouette: This technique creates strong drama and suspense, hiding details while highlighting form, encouraging the viewer’s imagination to fill in the blanks and intensifying the unsettling yet captivating visual tension.

  • moss and decay: Moss and decay elements convey the passage of time and the power of natural erosion, adding a sense of history and abandonment, immersing the viewer as though these creatures have existed in darkness for millennia.

More Prompt Tips & Tricks


You can explore further by combining the following prompt command for MidJourney:

  • --sv: There are six versions of the Style Reference feature in Midjourney version 7 when using images. Use the --sv parameter to choose between them. --sv 6 is default. --sv 4 is the old V7 sref model (prior to June 16, 2025). Using --sv 6 and --sv 4 may produce different style results.
  • --s: Default value is 100, can be set from 0 to 1000. The higher the value, the more detailed the image, and the closer the style may be to reality.
  • -niji 6: Using this command will give the image a more anime style.
  • --sw: Default value is 100, can be input from 0 to 1000. A higher value makes the style closer to the original.
  • You can now blend multiple --sref codes together (for example --sref 123 456 )
  • You can weigh individual codes or urls as follows --sref 123::2

This website stands out as one of the pioneering libraries I discovered in my AI art journey. What truly sets it apart is its comprehensive offering: not just unique style codes, but also intricate blends and full prompts. The inclusion of complete prompts is particularly valuable, as it's an artistic choice that many creators hesitate to share openly.

As a beginner in MidJourney, I struggled to create the style of images I envisioned and felt lost with keyword usage. This led me to create this website for sref codes and examples with prompts, aimed at helping newcomers easily generate high-quality images and find joy in their creative process.
