Its an interesting photo. I'm not sure where the subject is as you have three different points that I look at, the face, the light in the mirror and the "Cave in" on the t-shirt. The glasses have some spots that reflect the light and you've got a shiny nose. I think you have a decent idea of photography, but the whole thing just doesn't work for me.
This shot shows a lot potential, I might suggest that a different camera placement would have helped express this better, or course this is highly subjective, so it's just my two cents worth.
not the most flattering of poses I don't think. Glasses look very crooked and I'm sure you've heard about the light...too bright(IMO), draws my eye towards it and creates shiny spot on glasses, nose, and forehead.
I love the look on the face, and it's a quite interesting composition. I would rather the the light was not visible, the whole area below the face is slightly distracting.
Did you rotate the photo so we could read the guy's shirt better or for some other reason I don't get? Also, the bright light in the lower left corner is distracting.
