A mature man with a tall and straight posture, an elegant temperament, and slightly graying temples, has a gentle face and a calm look in his eyes that reflects the precipitation of years. He is dressed in a light camel-colored formal suit, with an open-necked light pink shirt underneath, and paired with light blue sheer socks. He has his hands behind his back, tilts his head slightly upward, and looks into the distance. He is in a top-floor study with a large French window, and the soft afternoon sunlight filters in gently through the curtains. In a classical oil painting art style, a medium format camera is used, with an aperture of f/5.6 and a shutter speed of 1/150. The overall color tone is warm yellow, with a slight vintage grain effect added.
