According to the [XXX theme], a collector's edition epic narrative poster is automatically generated: the huge and elegant silhouette of the side face of the character is used as the outer outline, and the complete world view, iconic scenes, character relationships, symbols, key buildings, creatures, props and atmosphere that best fit the theme are automatically grown inside the silhouette. The whole is not an ordinary collage, but an advanced silhouette filled narrative synthesis, with double exposure association, but more partial film posters and dreamy watercolor illustration fusion style; soft air perspective, light atomization transition, paper particles, white edges and brush marks, large areas of white, the layout restrained advanced, quiet, grand, sacred, nostalgic, poetic, legendary sense. Style, color, scene, and material are all automatically adapted according to the theme. All elements must be strongly bound to the theme, recognized at a glance, not cluttered, not hard collage, not template background, and not cheap fantasy materials. Exclusive signature "why" should be added to the screen naturally. As part of the poster design, the position is low-key but clear. It can be placed in the lower left corner, lower right corner or near the title. The style should be unified with the overall layout, like the author of the collection poster or the design signature. The signature is exquisite, restrained, and advanced. It should not be too large, destroy the composition of the main body, and it should not appear abrupt and cheap.
