Themed Poster Layout Design

Based on [XXX theme], automatically generate a collector's-edition epic narrative poster: a huge, elegant profile silhouette of a figure as the outer contour, inside which grows the complete worldview that best matches the theme, its iconic scenes, character relationships, symbols, key buildings, creatures, props and atmosphere. The whole is not an ordinary collage but a refined silhouette-fill narrative composite, with double-exposure-like association, leaning toward a fusion of movie poster and dreamy watercolor illustration; soft aerial perspective, gentle misty transitions, paper grain, dry-brush edges and brush marks, generous white space, restrained and refined layout, quiet, grand, sacred, nostalgic, poetic, with a strong legendary feel. Style, color, scenes and materials all adapt automatically to the theme; every element must be strongly tied to the theme and instantly recognizable. No clutter, no hard collage, no templated backgrounds, no cheap fantasy stock elements. Naturally include the exclusive signature "WHY" as part of the poster design, placed discreetly but clearly, in the bottom left corner, the bottom right corner or near the title, styled consistently with the overall layout, like the author's signature or design seal on a collector's poster; the signature typeface should be refined, restrained and high-end, not too large, must not disrupt the main composition, and must never look abrupt or cheap.
