Art style: Clay / Plasticine.
Full-length view, the entire figure visible from head to feet, standing upright and centered — a sharp-witted schoolboy about eleven years old, with a slim, slightly lanky build. He has a round, bright face with fair skin, a dusting of freckles across the nose, lively intelligent brown eyes, and short tousled chestnut hair with a cowlick at the crown. His expression is calm and knowing, one eyebrow lifted as if he has just noticed the obvious. He wears a neat navy school uniform: a buttoned white shirt, a slightly loosened burgundy tie, a dark V-neck sweater vest, grey trousers, and scuffed brown lace-up shoes. A canvas backpack hangs off one shoulder. He stands in a bright classroom with a chalkboard and wooden desks behind him, holding a single pencil thoughtfully between his fingers.
