Edit the first reference image. Keep exact composition, faces, number of people, body poses (both sitting), facing direction (both facing camera lens directly), screen-center positions unchanged. Modify only clothing, boat, background. Photo-realistic documentary photo (Canon 5D, 85mm, natural daylight). PERSON ON SCREEN-CENTER-LEFT (orig: wears red life jacket, has long hair) → REMOVE modern life jacket; clothing: short hemp jacket (duanhe) in natural beige or light brown, waist-length with short sleeves, loose trousers (ku) tied at ankles, dark cloth headwrap (zejin) wound around head; hair: tied in simple bun under headwrap; sits as input.

Style: photo-realistic, NOT painting NOT illustration. Wei Jin (220-589 AD) ONLY. CRITICAL: NO chairs (sit on boat floor mat); NO post-Wei-Jin hair (NO Tang high buns, Song parted, Qing braid, modern short cuts); NO Tang/Song/Ming/Qing/Japanese/Korean styles; NO cotton, modern fabrics, eyeglasses, watches, plastic inflatables.
