Art style: Goth Comic.
John Snow, the 19th-century English physician, shown full-length from head to feet, standing upright and centered — a serious, attentive man of around forty with an analytical, observant gaze. He has a lean, upright build, pale fair skin, a high forehead with short dark side-parted hair, trimmed dark sideburns and a clean-shaven chin. He wears a mid-Victorian dark frock coat over a buttoned waistcoat, a high white collar with a dark cravat, narrow dark trousers and polished black leather ankle boots. In one hand he holds a folded street map; a small medical notebook and pencil rest in the other. His expression is calm, measured and thoughtful, brow slightly furrowed in concentration. He stands on a wet cobblestone London street near a cast-iron water pump, gas-lamp light and faint fog around him.

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