I saw the image first as a thumbnail (well, duh, of course...lol,silly me) and thought it was a shot of the young man with a bunch of smoke blown into the frame. It does seem a wee bit dark to me. If you want to keep it that dark, maybe boost the contrast a bit in one way or another, so those low tonal values 'separate' from one another, just a little bit more. And I would think it might help to dodge the top of his head, just a bit.( Of course, these are just my opinions; I hesitate to comment much on the work of people who I think know what they are after, or what they're doing...you've started falling into that category more and more as time passes and you keep hitting the studio lighting stuff as hard as you have been.)
