Art style: 3D Pixar Animation.
Full-length view, the entire figure visible from head to feet, standing upright, centered — Kiryusha, a friendly 7-year-old boy adventurer standing beside his quad bike. He has short chestnut-brown hair, large warm brown eyes, fair light skin, round cheeks and a big kind gap-toothed smile. He wears a bright yellow zip-up jacket, dark navy-blue trousers and clean white sneakers, topped with a matching yellow safety helmet with a black strap. Slim, small child build with an eager, energetic stance, one hand resting proudly on the handlebar. Beside him is his yellow children's ATV quad bike with black detailing, black chunky tires and black seat. He stands on a wide sunny forest dirt road, tall green trees and dappled sunlight filling the sides, cheerful and ready for adventure.
