Portada de libro infantil

Illustrate the front cover of a children's picture book in soft watercolor on visibly textured paper. Render the character or subject described in the user request as an adorable central figure with rounded, friendly proportions, caught mid-way through a wholesome, cheerful action such as waving, smiling, or holding up a small treasure. Surround the figure with loosely painted foliage, tiny flowers, and gentle washes that bleed softly at the edges, keeping the palette tender and storybook-warm. Reserve the top of the cover for a large hand-drawn title in playful lettering, with a smaller subtitle beneath it and a modest author credit line to one side; take any title, subtitle, author wording, and language from the user request and render every glyph accurately without garbling — if none is given, invent short, charming wording that fits the scene. Include a visible book spine along the left edge with a slight printing texture so the image reads as a real physical picture book. Keep the composition balanced with generous breathing room. Do not add watermarks, logos, barcodes, or any rude or unsettling gestures — keep everything gentle and child-friendly.
