I still haven't had a chance to test the IA MRS yet dude. I'm fixing to though. The eagle symbol is positioned there because originally I had it a lil farther away and further up but while in game it got cut off by the UI border around unit cards. As for the skin and helmet paints, I'm using this as a comparison:
A user on the forums somewhere had uploaded this in a thread where a lot of people were discussing CA's vanilla unit cards before the game was released. I've got to add a "dirty" mosaic background to the unit cards too but I think it would look good like that. The horses are painted everything. Its similar to Red figure style pottery, well, kinda Lol.
