Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Ksyusha, a creative, sweet teenage schoolgirl around fifteen. She has a soft round face with warm fair skin, big bright hazel eyes, freckles across her nose, and a shy genuine smile with slightly rosy cheeks. Her chestnut-brown hair is tied in a loose messy side ponytail with a small paint-stained clip, wispy strands framing her face. Slim, slightly clumsy posture, one shoulder tilted. She wears a cozy mustard-yellow cardigan over a white blouse, a pleated navy skirt, striped knee socks, and scuffed white canvas sneakers. A colorful sketchbook is hugged to her chest, a pencil tucked behind her ear, faint smudges of paint on her fingers. She stands in a bright school corridor by a sunlit window, looking a little bashful yet warmly sincere.
