I agree with Bob. Nice gritty portrait.
I am normally not a big fan of the small pinprick catchlights but here I think it works.
Are those striations along the cigar smoke trails or is that some kind of special type of cigar?
I like the portrait, but the foreground area of the shirt looks a little "muddy" to me. If you toned it down a bit, perhaps adding a little contrast might help it.
