Character poster, vertical composition, double exposure, ink wash negative space AI Image Prompt

A character promotional poster titled "{argument name="poster title" default="INPUT NAME"}", designed in a unified vertical key visual composition (9:16). Each poster follows a hierarchy of large top and smaller bottom structure: the upper half features the most recognizable element of the character (head, facial contour, mask, or upper-body silhouette) as a dominant oversized visual, forming a highly identifiable silhouette. The middle to lower section contains the full character as a secondary subject, shown in a stable standing pose or with subtle movement, establishing the visual core of the composition. Inside the large silhouette and around the character, use a double-exposure and collage-style narrative composition. Multiple scenes, symbolic imagery, small character interactions, supporting elements, and environmental details are layered and blended into mist, ink wash, and negative space. The left and right sides include complementary secondary elements to create narrative tension and spatial variation. A continuous flowing visual line runs from top to bottom, connecting the main character, internal collage, and the large upper silhouette, enhancing cohesion and guiding the viewer's eye. The overall composition preserves large areas of negative space. Edges are treated with ink diffusion, soft blurring, and fragmented transitions, creating a balance between presence and absence inspired by Eastern aesthetics. The style is cohesive, refined, and restrained, emphasizing depth, storytelling, strong visual impact, and a consistent series-style poster language.
