Art style: Children's Book.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Olya, a teenage girl of about sixteen with straight glossy black hair falling past her shoulders, side-swept bangs framing a calm oval face with warm fair skin, dark expressive almond eyes and a faint gentle half-smile that hints at hidden feelings. Slim but sturdy build, quietly confident posture with one hand resting near her heart. She wears a fitted dark charcoal hoodie over a deep-plum long-sleeve top, slim black jeans, and clean grey-and-white lace-up sneakers on her feet. A small silver star pendant rests at her collar. She stands on a quiet balcony at dusk, soft violet twilight sky with early stars behind her, a low railing and potted plants at the sides.

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.
