yndaaa is good modeler yes.
also is it possible for you to make the wheels on the mining cart a little more round without drastically affecting the polycount?
The poly count would increase VERY fast, and I don't think its necessary for a small thing like that.
One thing I feel worried about is the poly count of the Lumberjack compared to the other items in the game, it seems like he is alot more realistic looking then anything else. And with the low resolution of textures required by torque I feel that the lumberjack is going to look very odd in the game.
