Art style: Children's Book.
Full-length view, the entire figure visible from head to feet, standing upright and centered in a dim hallway at dusk. A tired adult man in his early forties, medium build, slightly rounded shoulders from a long day. Oval face with a faint stubble, soft tired brown eyes with light shadows beneath, short brown hair tousled and slightly greying at the temples. He wears a rumpled grey wool coat over a dark olive sweater, faded blue jeans, and scuffed brown leather lace-up shoes. A worn leather satchel hangs from one shoulder; a key still dangles in his lowered hand. His posture shifts from relief toward unease — head half-turned, lips parted, listening. Behind him, muted lavender twilight falls through a doorway, a coat rack and a waiting envelope on a side table framing the quiet, wrong-feeling home.

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.
