A small fox carrying a glowing lantern through a gentle dark forest of friendly shadows. 2026 trade-cover trend: oversized structural typography, high-contrast palette, strong readability at thumbnail size. All cover text must be Japanese only; render the quoted title and author name in correct, complete Japanese characters. Book cover with title "まっくらもりのともしび" and author name "山田ひなた" rendered on the cover.. Workflow direction: Create the finished flat front-cover artwork itself, not a photograph or mockup of a physical book. The rectangular front cover must fill the entire output canvas edge to edge, viewed perfectly straight-on with the camera perpendicular to the artwork. Build a compelling genre-appropriate key image, readable title hierarchy, deliberately placed author name, short correctly rendered Chinese or English title text enclosed in quotation marks, strong silhouette at thumbnail size, and trim-safe breathing room for practical editorial use.
Style-specific direction:
Style: warm children's picture-book cover in hand-painted gouache with friendly shapes, expressive characters, and visible paper texture.
Subject: preserve the requested main character, action, and setting; keep every character age-appropriate, kind, and immediately readable.
Composition: portrait front-cover layout, one cheerful central character, simple supporting details, open sky or calm area for the title, strong small-thumbnail silhouette.
Lighting or Color: bright saturated primary colors balanced with soft natural greens; cheerful daylight and gentle rounded shadows.
Typography: render the exact quoted title once in chunky playful rounded lettering and the exact quoted author once in small friendly type; keep both crisp and correctly spelled.
Output format: flat front-cover artwork only, filling the canvas edge to edge and viewed perfectly straight-on; no physical book object, frightening imagery, crowded cast, spine, pages, back cover, perspective, mockup, badge, logo, watermark,
