Keep the EXACT same man and face as in the reference (same identity, ordinary real Russian man, 50 — Tamara's colleague Sergey). Restyle for a birthday but keep it realistic and understated: a clean shirt under a light jacket (soft colour), tidy hair, a cheerful good-natured genuine smile — not exaggerated. Pleasant soft warm natural daylight, gentle natural colours, clean soft neutral background, no text. Friendly, authentic, happy. Photoreal, head and shoulders, 50mm lens, shallow depth of field, high detail.
