Lower arms, lower legs, torso, head, hands - Iron Man Mk46
Upper arms, upper legs - Iron Man disco armor
Shoulder pads, waist discs - Iron Man Extremis armor
Shield - Captain America

I did not like the Extremis version of Iron Patriot (too skinny), I do not think the Iron Man 3 Iron Patriot can stand in for a Dark Avengers display (too blue, and it is Rhodey! He is a good guy!). So I put this together. Slightly modified the head sculpt to make it look a little more sinister, sculpted the star on the chest with Apoxie.
