Well, as of so far, all of the clothing will be based off the player model. We are looking for a model, but, we haven't found anything. I agree, we do need more detail and shading, because the model itself is pretty basic. For a starting model, it's good. However, it would be best to stick with one model for the whole game, instead of drastically changing the model during an update.
So, if you have a player model, post it!
