Such an awesome character. I love it. Though, if I were to critique, I'd say his face could use a little more sheen, or even sweat. A corduroy blazer would be pretty damn brutal in the southern heat.
Great job so far, but it looks like you made the blazer too long compared to the concept you're working from. Also, get in there and work those fingers, it looks like you've got some minor issues with a few of them.
