Art style: Children's Book.
A tiny, athletic young male kitten with sleek black fur and striking bright yellow eyes. He has a very streamlined, energetic posture, leaning forward as if ready to sprint. His ears are slightly swept back, and he has a long, expressive tail. He looks playful and mischievous. The lighting is bright outdoor sunlight, catching the glossy sheen of his dark fur, set against a vibrant green lawn with scattered autumn leaves.

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.
