Art style: Pencil Sketch.
Full-length view, the entire figure visible from head to feet, standing upright, centered on a tanker's steel deck by the ship's rail with the painted hull and open sea filling the sides. A stern sea captain of about sixty, roughly 178 cm, sturdy broad-shouldered build with a slight paunch. Weathered tanned face, deep forehead creases and crow's-feet, sharp piercing pale-grey eyes under thick brows, thin lips set in a firm line. Full, dense silver-grey beard and matching close-cropped hair beneath a navy peaked captain's cap with gold anchor badge. Dark navy double-breasted uniform jacket with gold-braid cuffs and epaulettes, crisp white shirt, black tie, matching trousers, polished black leather deck shoes. He crosses his arms, chin raised, skeptical scowl as if inspecting sloppy work.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Pencil Sketch" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Pencil Sketch". 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 "Pencil Sketch" idiom, not in any other medium.
