Me? Do Team Fortress 3?

I've always wanted to design characters for video games. Team Fortress 2 is a real gem despite the fact that I've never played it before. But I've always admired the class designs and I've wanted to do an "alien" take on the game. Here are some little sketches.

Here one of my first ones, the Alien Medic and Heavy. The Medic looks so much like a Muppet and I love that! It adds to the doctor thing he's got on him. I'm fond of the Heavy's Clothes, but the face needs to be more distinguished from his human counterpart.

Space Pyro! Awesome but could be awesomer!  His suit should defiantly change. I do want to avoid having him look like The Fury, from Metal Gear Solid 3, though.

The Space Spy design was insprired by that lizard guy from "Monsters Inc." The camo suit helps with cloaking and disguises and with that natural tail knife or barb, this spy is very alien-y!

And the Alien...take a wild guess. He's pretty Chewbaca-y. This has to be my favorite design especially the hat!
