Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Nastya, the cheerful energetic eldest daughter, a lively girl of about nine or ten. She has a round friendly face with warm light skin, rosy cheeks, bright expressive brown eyes and a wide happy grin showing a small gap in her teeth. Her chestnut-brown hair is gathered into two bouncy high ponytails tied with cheerful ribbons, a few loose strands framing her face. Slim, athletic, energetic build. She wears a bright sporty outfit: a colorful short-sleeved tee, comfy track jacket tied around her waist, denim shorts over leggings, and chunky lace-up sneakers. One hand waves eagerly, the other rests on her hip, mid-bounce on the balls of her feet. Behind her a sunlit outdoor tennis court with a distant city skyline.
