Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Kostya, a cheerful four-year-old boy, small and slightly chubby with a round soft face, big bright curious eyes, rosy cheeks and a wide gap-toothed grin bursting with delight. He has short tousled light-brown hair with a little cowlick sticking up. He wears a bright red-and-yellow striped short-sleeve t-shirt, comfy blue denim overall shorts with a small star patch on the chest pocket, and colorful mismatched socks tucked into little white-and-orange sneakers with velcro straps. He stands with feet apart in an excited pose, one arm raised pointing upward as if spotting something amazing, mouth open mid-laugh. Behind him a cozy sunlit child's bedroom scattered with toy robot parts, gears and screwdrivers on the floor, hinting at building Wall-E.
