15 Halloween Sticker Sheet Studios

Generate a polished 16:9 Halloween sticker sheet containing exactly 15 separate designs in a clean 5-column by 3-row grid. Five inputs control the theme, character personality, accessories, six-color palette, and composition direction. Each result uses flat vector-like shapes, bold black outlines, crisp white die-cut borders, consistent spacing, and a pure white background. Ideal for seasonal sticker concepts, digital crafts, UI assets, and artwork prepared for later vector refinement.
