Alien Cowboy VS Zombies

Character of the Week: 'Zombie-killing, Dinosaur-riding Cowboy Alien'
Who can resist such a cool topic?
Well, I gave it 4 hours of love! I tried to break away from my usual realistic approach and tried to make it more stylized.
The left zombie seems weird in this scenario, I know...
I don't wanna put this under mature content >< (its just a walking brainless dead body...)

yeah, he looks a bit like Davy Jones from Avatar with a shotgun.

edit: lol wth? He DOES look like Cad Bane from Clone Wars like people pointed out. But I swear I didn't know that character before!
