Art style: Cinematic Realistic.
The same teenager's room at evening, quiet atmosphere. 17-year-old Lena (neutral green sweater, dark trousers) sits alone at her desk. An open book and notebook are in front of her. She holds a pen, looking at the page with a puzzled, slightly lost expression, then looks slightly aside, trying to find a starting point. Cinematic photorealism, soft moody lighting, vertical 9:16.

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