Art style: 3D Pixar animation.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Sasha, a young girl of about eight, Alex's little sister. She has a small rounded face with large expressive hazel eyes, a sprinkle of freckles across her button nose, and warm fair skin. Her light auburn hair is tied into two loose pigtails with slightly frizzy strands framing her face. Slender, petite build. She wears a soft lavender long-sleeved shirt, denim overall shorts with one strap slipping off her shoulder, striped knee socks, and scuffed pink canvas sneakers. Her expression is a mix of wide-eyed curiosity and nervous fear, shoulders slightly hunched, one hand clutching the other near her chest. She stands in a dim hallway at night, a faint glow from a doorway behind her.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D Pixar animation" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D Pixar animation". 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 "3D Pixar animation" idiom, not in any other medium.
