Prompt
Create one finished children's picture book front book cover in a single generation, 1024:1024 portrait composition, flat cover artwork only, never a book mockup. Exact title text: "MOUSE BUILDS A BOAT". Exact author text: "LENA WU". Subject: a determined mouse building a walnut-shell boat beside a puddle harbor. Composition: preserve a clean title zone, one dominant focal idea, readable silhouette at thumbnail size, and professional trade-publishing hierarchy. Style: whimsical hand-painted gouache, rounded shapes, expressive friendly characters, simple readable scene. Color and light: bright friendly colors with warm paper texture and gentle contrast. Typography: chunky rounded hand-lettering that remains crisp and correctly spelled; render the exact title and author once only, with correct spelling, clean kerning, no extra words, no duplicate letters, and no invented publisher marks. Constraints: print-ready front cover, polished visual hierarchy, coherent anatomy and perspective. Avoid: malformed text, repeated author names, extra logos, watermarks, borders, 3D books, hands holding a book, or horizontal mockups.
