Prompt: Turn the input character into a vertical double-exposure art poster: a layered, flowing collage in polished anime illustration with a clear focal hierarchy and bold, clean color.

The hero: one full-body figure of the character is the anchor and the only faithful rendering, with the input's face, eye color and shape, expression, hairstyle, hair color, outfit, accessories and pose. Keep it anime, not photoreal, and keep its face and eyes crisp. It fills roughly half to two-thirds of the poster's height: clearly the star, never filling the frame, never lost in the layers.

The stack: above the hero, a large graphic head or face treatment filled with double-exposure imagery; to one side, a faint ghosted profile or partial echo. These two are free, stylized echoes rather than copies; vary their placement and content per character. A vertical flow links all three into one read, with enough negative space to breathe.

The technique: true double exposure. Scenes, textures and silhouettes show through the character's form and hair, and light bleeds between the layers so they read as fused light rather than a flat overlay. Draw the layered imagery from the character's own world: drifting clouds, ink-wash diffusion, environment fragments, small symbolic objects and micro-scenes, kept sparse enough that the character stays clear. Edges dissolve in ink diffusion and soft transitions.

Color: two or three hero hues keyed to the character, luminous and high-contrast against clean white or neutral space. Where layers overlap, colors stay clean, never muddy or grey. A poetic, Eastern-poster finish, like one piece of a premium poster series.

Avoid: a second faithful full copy of the character in the echo layers; a flat single-layer portrait with no depth; cluttered collage that buries the hero; garbled text, watermarks or frames; warped anatomy or extra fingers.
