Ace, just stick with your normal agenda for this mod, and trust me, it should be a hit!
I do suggest you not necessarily make more MP models, but skin the one you have to add some more variety in multiplayer!

The player models are a bit too round. This becomes even more evident in your wireframe... create some bulges in the arms for muscles, move the verts around a little... Things in general look great though. Those hands, not to mention the player models generally look great. (Ruthven should take a good look, lol...)

Don't touch the player models. They're fine, you're really not going to get any noticable or needed detail if you work on them further.
