the teeth and the eyes are the only things that seem slightly 'off'. Overall, this is AMAZING, and super realistic! You did a great job of capturing the character!
Now, with the eyes...They seem a little...well.. 'derp'. idk if that was intentional for the drunken look or not, but one is looking forward and the other is looking a bit to the side.
The teeth, as someone stated on the first page, are a little bit too low.
Again, I love the way this turned out! Great job!
