Faction Color Test - Rear

Front pic here.

 

So I've been experimenting with colors for over a month now, and this is probably my favorite so far. My goal is to have 3-6 schemes to have on hand for my gaming group, with each faction having 2 copies of 3 different frames. Above is SuspendedAnimation's Jumpmaster and a modified version of the sylince's Super Chub. Any recommendations on colors and a 3rd possible frame that meshes well with the existing 2 would be most welcome.
