Nice, but a bit too soft in my opinion... you may have done that purposefully, but the beard and hair, I think, want this picture to have more clarity. Background lighting is awesome, giving the left half of the image great emphasis.
I like the "in your face " sense of it. The lighting seems just a touch harsh. I might do a bit of sharpen on the eyes- just a bit. I like that your head is slightly cocked, to create an almost horizontal line. Great cleft. ;~D
Good lighting here and the small catchlights in both eyes are good. I like the composition and expression. I think this works very well in black and white.
