Art style: 3 d pixsar.
The girl alone at her desk, focused and calm, working confidently in complete silence, the timer showing 15 minutes glowing softly, she looks like the proud owner of her desk and notebooks. Clean bright natural light.

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.
