Let's see, Scout's a fox, Pyro's a dragon (presumably), Heavy's a bear (supposedly; I've neither seen you draw him nor played the game with the mod{never played the game, period}), Demoman's a wolf, Medic's an Alsatian, and Sniper's a Kangaroo. Any ideas for the others?

Oh wow, I haven't laid a finger to any art projects in years. Simply haven't had the creative insight to continue. Though I've been looking to someday do a remake of the Demowolf, was thinking to do a badger for Engineer, stag or another hardy creature as Soldier, and perhaps a panther or tiger for Spy.

TF2 is a great game, without a doubt. Lots of things to do in there, but I never followed through to make the icons or put it in the game. I'll need a lot more practice in my artistic capabilities before I'm ready to deliver I think, but it's on my mind to finally finish this work.

Don't think I'll ever do the modeling though lol, I have no clue how to even begin. There's already a pretty good fox skin by JFox for a Scout, and supposedly a grizzly Heavy somewhere (or polar bear, not sure). But a friend of mine is nudging me to continue and finish it out, so we'll see what comes this summer :P

I wish you the best on the practice. You'll probably want something without antlers for the Soldier (unless you plan on giving him a hat which will accommodate them). And I'd probably go with the panther for the Spy. Up to you though, you could even do both if you so desired.
