The image shows a man sitting at a wooden desk in a lecture hall. He is wearing a blue long-sleeved shirt and a red lanyard around his neck. He has a watch on his left wrist and is holding a red pen in his right hand. He appears to be writing in a notebook with a pen. In the background, there are other students sitting at their desks and a large mirror on the wall. The overall atmosphere of the image is one of concentration and focus.
