Maybe Tony Stark was inspired by Captain America after the events of The Avengers.
I could accept that explanation...except the way the colors are arranged makes me think of a mid-level fan-made costume, where the general build of the parts is good, but the paint and colors are atrocious
(Note: That's not a crit on fan-suits, it's the fact that it's very hard to get the right sort of metallic, bright glossy look of the props without having a lot of experience in auto paint.)
And WTF is up with those gauntlets? Those look like they're made by Nerf by the way theyre painted.
