Okay, okay. I've done an awful lot of these, but I really really really really like this one. I think I nailed the look.
In case this is the first one you're seeing, this is my version (what I see in my head during his parts on the album) of The Protomen's version of Dr. Albert Wily from their magnum fucking opus (so far) Act II - The Father of Death. I've drawn quite of few of these, but this one is, by far, the best.
UPDATE: I made it even more awesome.
