I think Iron Man looks exceptional, pretty much perfect and a lot better than his AoU costume which is still very much washed out.
Captain America's face and skin texture looks a lot better in his CW costume, although the textures on the rest of his costume just don't look as sharp and detailed as his AoU costume. I feel the texture will be similar to Blade's San Francisco costume which is also pretty low on sharpness and detail. We'll see how it looks in game but right now it looks muddy. Still a pretty good costume.
