Just an opinion(and I don't mean to say that this isn't excellent already) but I think that perhaps it would look even better you only had the one ACU on the left in the picture in the center(a bit like the center piece to the moment of leadership in the battle).
Very cool, very cool stuff. I always thought they needed to add some melee to the game. Would love to see the ACU with a big ol energy sword or like, thermal hammer or something. Anyway. Great work dude.
