Holy sh*t, this is the most epic thing ever. I have to say that he's one of my favorite characters by now and this is just so him. This piece of art shows the side of him I first saw, it gives me the feelings I first had; he looks so intimidating, so strong.
You've really done an amazing job on this one and captured this side of him perfectly into art.
(I wish I could put this one on my wall because it's so amazing!)
