Prompt Template
**“Analyze the provided images and extract ONLY the unified visual style.
Although the image is composed of a grid of images, treat them as one cohesive style reference - do NOT describe or reference the characters individually, and do NOT mention the panel layout or that there are four sections.
Focus exclusively on the global stylistic qualities, including:
illustration style (flat, graphic, painterly, vector-like, etc.)
contrast behavior
Background style and color
shapes, proportions, and stylization
line quality and outline treatment
shading/lighting approach
texture use (if any)
mood and visual tone
pattern usage
any recurring artistic conventions
Hex colors and their use (skin tone, background, patterns, etc)
Produce a clean, standalone style description that can be used to generate new images in the same style but with entirely new characters or scenes.
DO NOT mention specific characters, poses, clothing, or objects from the original image—ONLY the style.
Output this in two parts:
STYLE DESCRIPTION (4–7 sentences):
A detailed explanation of the unified artistic style.
KEY STYLE TAGS (10–20 keywords):
Short labels that summarize the style.
Hex colors
