Art style: Children’s Book.
A small fluffy yellow duckling with soft golden feathers, large round dark eyes full of wonder, a tiny bright orange beak, and slightly oversized orange webbed feet. He has chubby cheeks, a round body, and an innocent smile. Dilly is curious, kind, and cheerful. Children's book illustration style, watercolor storybook, soft pastel colors, cozy atmosphere, cinematic lighting, highly detailed, adorable and consistent character design.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Children’s Book" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Children’s Book". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Children’s Book" idiom, not in any other medium.
