A pencil drawing a rainbow bridge that tiny forest animals cross. 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 "まほうのえんぴつ" and author name "ひらのあすか" 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 one compelling genre-appropriate key image on a single strong subject in a single scene — never a collage of competing motifs. Follow the 2026 trade-cover direction: oversized structural title typography treated as part of the artwork, a high-contrast palette, an author name placed deliberately and secondary to the title, short correctly rendered title text in the requested language enclosed in quotation marks, and a silhouette that stays readable at 100-pixel thumbnail size in a two-second scroll, all with trim-safe breathing room.
Style-specific direction:
Style: warm children's picture-book cover in hand-painted gouache with friendly shapes, expressive characters, visible brush strokes and paper texture — a handmade feel, never over-polished digital gloss.
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, or duplicated text.. Avoid: physical book, 3D book, book mockup, product mockup, spine, pages, page edges, back cover, perspective view, angled cover, tabletop, pedestal, hands holding a book, room scene, drop shadow around the cover, misspelled title, crowded typography, weak focal point, busy collage of competing motifs, washed-out low contrast, text too close to edges, unrelated imagery, garbled author name, misspelled or duplicated title, misspelled author, frightening expression, crowded cast, photorealism, 3D mockup, spine, watermark
