Prompt
A brave guinea pig in a bottle-cap ship sailing a bubbly bathtub sea. 2026 trade-cover trend: oversized structural typography, high-contrast palette, strong readability at thumbnail size. All cover text must be English only. Book cover with title "Captain Button" and author name "Rex Almeida" 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
