FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D Pixar-style animation" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D Pixar-style animation". 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 "3D Pixar-style animation" idiom, not in any other medium.
