Create a high-aesthetic 9:16 "silhouette universe / collector-edition narrative poster" based on [Theme]. Do not default to common containers such as bottles, hourglasses, glass domes, or pocket watches. Instead, choose the most symbolic and visually powerful outer silhouette for the theme: an object, building, gate, tower, arch, dome, staircase, corridor, statue, side profile, eye, hand, skull, wing, mask, mirror, throne, ring, crack, light curtain, shadow, geometric form, spatial cross-section, stage frame, abstract symbol, or any more creative silhouette that best represents the theme.
The goal is not to simply put a world inside an object, but to let the theme universe grow naturally inside the silhouette, along its edges, and through its transparent or pierced relationships. The silhouette must be elegant, recognizable, and dominant in the composition. Inside or near its boundary, build a layered narrative world closely related to [Theme], including iconic scenes, key architecture or spaces, symbols and metaphors, traces of characters or civilizations, foreground/midground/background depth, and an emotionally charged atmosphere. Doors, stairs, bridges, water, smoke, roads, light sources, ruins, mechanical structures, landscapes, abstract forms, creatures, and props should feel unified and naturally integrated rather than pasted together.
The final image should feel like a premium collector poster: a stable large shape, a main silhouette readable at first glance, an inner world with depth, structure, and breathing room, rich detail without overcrowding. Add small human silhouettes, distant buildings, beams of light, doorways, bridges, steps, corridors, reflections, skylights, or far structures when useful for scale, story, and epic mood. Blend collector-edition movie poster design, high-end narrative visual design, dreamy watercolor texture, and refined paper-printing quality. Emphasize paper grain, feathered edges, watercolor brushwork, soft diffusion, aerial perspective, mist, selective volumetric light, light passing through fog, generous blank space, and restrained layout.
Let the palette be theme-aware, unified, tasteful, low-saturation, and premium, such as black-gold-gray, cool blue-gray, misty white-gray, brown-red with rice white, dark copper, aged paper, deep ocean blue, twilight purple, or silver gray. The first glance should reveal strong theme identity and a memorable silhouette; the second glance should reveal a complete narrative world; close viewing should still reward detail and aftertaste. Avoid generic backgrounds, hard collage composition, template fantasy assets, video-game-ad energy, excessive cartoon styling, or realism that destroys the poetic atmosphere. If suitable, add a low-key title, number, signature, or mark as part of the poster design, but never let it overpower the image. Output aspect ratio: 9:16.
