Create a whimsical children’s‑book cover titled “Valentin and the Chocolate River”. Center the scene on a curious 7‑year‑old boy (short brown hair, pajama‑top, no backpack) peering through a slightly ajar attic door that glows with warm, golden light. Beyond the doorway stretches a bright, sun‑lit forest: tall trees, blueberry bushes, and a smooth, flowing river made entirely of liquid chocolate winding far into the distance. On a low branch near the riverbank, a small, friendly green dragon (soft scales, delicate wings) watches the boy with a gentle smile. Beside the dragon, a red‑panda professor in round glasses holds an old, rolled‑up map, her expression curious and welcoming. The title “Valentin and the Chocolate River” sits at the top in a playful, hand‑drawn serif font, rendered in gold‑yellow letters with a subtle chocolate‑texture overlay. The author’s name appears at the bottom in a smaller, clean sans‑serif typeface. Color palette: warm sunrise oranges and yellows for the attic light, deep forest greens, vivid blueberry blues, and rich, glossy chocolate brown for the river. Lighting should be soft yet radiant, emphasizing the contrast between the dim attic interior and the luminous forest beyond. Style: modern story‑book illustration with semi‑realistic textures and a gentle depth‑of‑field, suitable for an Amazon UK paperback thumbnail. Include subtle decorative flourishes such as tiny twinkling stars in the attic ceiling and a thin border of stylized See more
