Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Polina, a 10-year-old girl, the responsible older sister and the family's voice of reason. She has a rounded, bright face with fair skin, big attentive hazel eyes behind thin round glasses, light freckles across her nose, and a calm confident half-smile. Straight chestnut-brown hair falls to her shoulders, neatly held back by a headband. Slim, upright posture with a tidy, alert bearing. She wears a crisp light-blue collared blouse under a navy pinafore-style dress, white knee socks, and clean red buckle Mary-Jane shoes. A small satchel with a book peeking out hangs on one shoulder; she holds a pencil, mid-explaining gesture. Behind her, a warm, slightly messy family living room with a stray robot vacuum on the floor.
