Art style: Children's Book.
Full-length view, the entire figure visible from head to feet, standing upright and centered — a calm, caring middle-aged man in his early forties. He has a warm oval face, light-medium skin, soft friendly brown eyes framed by gentle laugh-lines, and a kind, reassuring smile. His short dark-brown hair is neatly combed, lightly greying at the temples, and he wears a trimmed short beard. His build is average and approachable, slightly softened, with relaxed shoulders. He wears a comfortable soft blue button-up shirt with sleeves rolled to the forearms, a light grey open cardigan, beige chino trousers, and clean brown low leather shoes. One hand rests gently over his chest while the other holds an invisible bottle. He stands in a bright, cozy home nursery with pale walls and a soft rug underfoot.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Children's Book" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Children's Book". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Children's Book" idiom, not in any other medium.
