Static camera, no camera movement. The man remains standing in the same position and looks forward. He slowly develops a very subtle, restrained smile, emotionally ambiguous, somewhere between sadness and happiness. The smile should be minimal and natural, mostly visible in the eyes and slightly at the corners of his lips, not a broad happy smile. He naturally lifts his left hand and gently adjusts the shoulder bag strap hanging over his left shoulder, then relaxes his hand. His body movement is subtle and realistic, with natural breathing, tiny head movements and blinking. Preserve his exact face, hairstyle, clothing, body proportions, lighting and airport background from the reference image. No changes to the environment or composition. No new people or objects. No camera movement, no zoom, no pan, no tilt. Cinematic, realistic, smooth natural motion.
