The shading on his upper lip was an on again, off again process, I did it in layers. Overall I think it took me an hour and a half to do the whole thing. The best shading was on the torso, but you can't really tell on the scanned image here because the depth seems to have been lost.
It's one of the better drawings I've done, and one of the only times I've been somewhat successful with a wrestler. I have one of The Undertaker I did last Summer that I drew too that looks pretty good. As for the best drawing, it has to be a self portrait I did as a final for my drawing class the first semester of college. We had to spend a limit of 13 hours on it, it's a self portrait, and I'm clutching a lucha mask I bought at hot topic. I'll see if I can scan that in over the next few days as well.
Thanks for the comments guys.
