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 round-cheeked with a soft toddler build and slightly chubby hands. He has warm fair skin, big bright curious brown eyes, and short tousled light-brown hair with a little cowlick sticking up. His round face beams with wide-eyed delight and an open, gap-toothed grin. He wears a cozy oversized sky-blue t-shirt printed with a tiny cartoon rocket, comfy grey jogger pants, and small white-and-red sneakers with velcro straps. His posture is playful and excited — arms slightly raised, leaning forward on tiptoe as if about to discover something wonderful. Behind him is a warm sunlit child's bedroom cluttered with toys, scattered robot parts, bolts, and a workbench. Bright, friendly, wholesome mood.
