Art style: 3 d pixsar.
Father as a calm helper, sitting relaxed nearby, checking the finished notebook and smiling proudly at his daughter, giving a thumbs up. No hovering, relaxed body language, warm supportive atmosphere.

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