I like it, he looks rather dumb but I guess that is the look you're aiming for.

Gotta love Zbrush aight.

How did you do the "beard" btw? Did you just use a alpha and had a darker colour to it or did you texture it in a other software?

And it looks like he got a little beard on his lips.

Perhaps the right eye should go inwards as he gets hit, he looks to focused at the moment.

Keep it up!
