Doctor Professional Portrait

Create a 4:5 vertical professional doctor portrait. A middle-aged Chinese male doctor in a clean white coat stands beside an examination table in a medical consultation room, holding a stethoscope in one hand and a blank medical folder in the other, with a warm and trustworthy expression. Soft-focus examination lamp, pale blue curtain, sterilization cabinet, and a small plant in the background, realistic but tidy. Large soft window light mixed with a slight cool clinical ambience; white, pale blue, and light wood tones, clean but not cold. Real commercial photography, 70mm lens, half-body composition, natural skin, realistic body proportions. No readable text, logo, watermark, hospital name, badge text, or brand mark anywhere in the image.
