Epic Poster with Profile Silhouette Worldbuilding

Automatically generate a collector's edition epic narrative poster based on [XXX theme]: a huge, elegant side-profile character silhouette forms the outer contour, while inside the silhouette, the complete worldbuilding most suited to the theme organically grows—iconic scenes, character relationships, symbolic motifs, key architecture, creatures, props, and atmosphere. The overall image is not an ordinary collage, but a refined narrative composite filled within a silhouette outline, with double-exposure-like associations, leaning more toward a fusion of cinematic poster design and dreamy watercolor illustration; soft atmospheric perspective, lightly misted transitions, paper grain, reserved white edges and brush marks, large areas of negative space, restrained and sophisticated layout, quiet, grand, sacred, nostalgic, poetic, and strongly legendary. The style, colors, scenes, and materials should all adapt automatically to the theme. Every element must be strongly tied to the theme and instantly recognizable; avoid clutter, forced collage, template-like backgrounds, and cheap fantasy assets. Naturally include the exclusive signature “WHY” in the image as part of the poster design, placed subtly but clearly, either in the lower left, lower right, or near the title. Its style must be unified with the overall layout, like an artist credit or design seal on a collector's edition poster; the signature typography should be refined, restrained, and premium, not too large, not damaging the main composition, and not looking abrupt or cheap.
