Art style: 2D Hand-drawn.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Kai, a ten-year-old European boy, slender and small-boned with a pale winter complexion touched pink at the cheeks and nose. He has tousled sandy-blond hair falling in soft strands over his forehead, bright blue eyes, and fine delicate features. His expression has just turned cold and distant — a faint frozen frown, lips pressed, eyes glinting hard and detached, warmth draining from his face. He wears a woollen rust-red coat with brass buttons over a cream knit sweater, dark-grey short trousers, thick striped knee socks, a loosely knotted blue scarf, and scuffed brown leather lace-up ankle boots. Snowflakes dust his shoulders and hair. He stands on a frost-rimed cobblestone street beside a snow-laden rooftop garden, a single sled rope hanging from one mittened hand.
