Art style: Criminalistic.
A clearly recognizable likeness of Петров — keep their real face shape, skin tone, hairstyle, build and any signature look (hair, kit, number). Седые редкие волосы, морщинистое, вечно недовольное лицо. Пронзительные, подозрительные глаза. Одет в старый, застиранный домашний халат.

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