Candid Train Photo to Studio Portrait

Using the provided reference image, turn this candid train photo into a clean professional studio head-and-shoulders portrait of the same person. Keep the same hairstyle, shirt-and-sweater outfit, and overall identity cues, but remove the headphones, train window reflection, table, thermos, book, and all travel context. Reframe the subject so he is centered and facing the camera in a neutral upright pose, cropped from mid-chest upward. Replace the background with a plain muted blue-gray studio backdrop and use soft even portrait lighting for a polished corporate profile photo.
