After reading Swizzle's (extremely helpful) post about textures in TF2, I decided to (for the most part) redo the textures on the shield. It's still subject to change, but I think I've got at least a grasp on what I want it to look like. Here it is for each team, respectively.
Also, I've gotten a little work done on the primary replacement, which is supposed to be a pump-action shotgun of sorts. The mesh is pretty far from done, still, but I've gotten enough done to at least post. So here's that.
