This is actually pretty awesome and I could see it being used as a design for a futuristic version of our Star-Spangled Super-Soldier. I would also suggest that the gauntlet shields could have a photon-based expansion ability to block heavier artillery, with the gauntlet shields as the centerpiece of the photon force field. Hell, I would even suggest that the gauntlet shields could be used as projectile weapons in the vein of Batman's Batarangs, only launched directly from his wrists. Of course, the face mask should be somewhat retractable in the event he needs to make a speech and be inspirational, since nobody's going to put their trust in a scary faceless-looking guy even if he is wearing the American flag colors.
I like the clean look of it. And the helmet covers his Identity well. I kinda agree anout the mini shields would like to see a gauntlet of some kind. Like his ole energy one when he lost his shield under the ocean. That would let him use it as a launching weapon. But good over all design and matching color. The stronger black in it gives him a Dont mess with me feel. Great job!
