Art style: Children's Book.
Мальчик 12 лет, лучший друг Лины. Русые волосы, умные глаза за очками в тонкой оправе. Одет в рубашку-поло и брюки. Выглядит более серьезным и рассудительным.

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.
