Based on [Theme], create a high-aesthetic 9:16 vertical work in a silhouette-universe, collector-edition narrative poster style. Do not default to common containers such as bottles, hourglasses, glass domes, or pocket watches. Instead, choose the most meaningful main silhouette for the theme: it may be an object, building, gate, tower, arch, dome, stairwell, corridor, statue, side profile, eye, hand, skull, wings, mask, mirror, throne, ring, crack, light curtain, shadow, geometric structure, spatial cross-section, stage frame, abstract symbol, or another more creative thematic outline. The outline must be clear, elegant, memorable, and central to the composition.
Let the theme's complete world naturally grow inside, around, on, or along the boundary of that silhouette, as if a full narrative universe is attached to a symbolic form. Include theme-specific landmark scenes, architecture or spatial structures, symbols and metaphors, character relationships or traces of civilization, foreground-midground-background depth, emotional atmosphere, and narrative details such as doors, stairs, bridges, water, smoke, paths, light sources, ruins, machinery, nature, abstract forms, creatures, or props. Everything must feel unified and layered, not like collage, hard cropping, stacked assets, or a template background.
Make the poster feel quiet, grand, poetic, sacred, nostalgic, mysterious, and collectible. Use a stable large composition, strong silhouette memory, rich but breathable internal detail, small silhouettes or distant structures when useful for scale, and restrained negative space. Blend collector movie-poster composition, premium narrative visual design, dreamy watercolor texture, paper grain, dry-brush edges, soft bleeding, atmospheric perspective, mist, subtle volumetric light, and refined print layout. Choose a restrained low-saturation palette that best serves [Theme], such as black-gold-gray, cool blue-gray, mist white-gray, reddish brown with warm ivory, dark copper, aged paper, deep sea blue, dusk purple, or silver gray. Avoid cheap neon, plastic digital gloss, cluttered saturation, ordinary background splicing, stiff cutouts, generic fantasy assets, game-promo feeling, excessive cartooniness, or hyperrealism that loses the artistic mood. Optional subtle title, edition number, signature, or seal may be included only if it supports the collector-poster design without dominating.
