The background is cluttered, the picture directly behind the subjects' head is distracting, I can't decide if that thing on the RH side is a radio or a humidifier, the table and poster(?) are angled as if there's a perspective shift, but the subject is square to the camera, I can't figure out what's in front of him, the wallpaper is twenty years past its prime, and the image is irrecoverably noisy.
ditto - adjust levels in PS, the noise is great esp. with the vintage looking wallpaper and rough looking subject. Pretty good shot, though. i think the top of the head being cropped was a bad move, too. can you uncrop the top?
If the top of the head can't be uncropped, how about cutting off more of it with a 2:3 ratio? I can't believe I'm saying this, but I'm worried that it will remove some of the clutter and weaken the shot.
