Cobra is looking like a gray Retaliation, I think
I've done some body modelling a long time ago, though I wasn't very succesful because the same problems my structure models weren't succesful: Couldn't get them ingame
But I think your models will be jsut fine with some work, keep improving your skills!
And good luck!
If your referring to that annoying teamcolor/animation error I know how to fix it
must be made in blender
select all faces in edit mode go to object mode make sure the object is still selected
go to the file make copy of the pie file, now open with note pad
copy the line that starts with Texture 0 blah blah blah texpage "copy that line"!!!
now open that file with pieslicer & go to the texturing panel click the box "Teamcolors" so it is checked
And set "frames" 
open the file in note pad again & paste over "No Textures"
now make a copy of that
import in Blender it should be fixed now
..if you weren't referring to that... oh well
