Photorealistic cinematic portrait of a young imperial investigator, Andrey Koloss, age 19-20. He has a realistic Slavic aristocratic appearance with a pale Eastern European face, slightly imperfect youthful features, and intelligent grey-blue eyes showing a hint of tiredness. His gaze is observant and analytical. Dark, messy wavy hair falls naturally over his forehead. He wears a dark wool overcoat. The setting is a foggy 19th-century street in an alternative imperial Saint Petersburg, with gas lamps glowing through the dense fog, creating a moody, noir atmosphere. The style should be a realistic, live-action film still, with dramatic shadows, a muted color palette, and high detail, matching the provided reference image.
