That mask reminds me of an old Iron Man faceplate.
Sometime between the "pointy-eared" mask armor designed by Steve Ditko (it was the FIRST red and gold Iron Man armor) and the classic 1966-1985 Iron Man armor (the suit he wore during the first "Tony the Alcoholic" storyline) there was another armor similar to the "classic suit" that had a helmet faceplate with riveting around its edges.
Props to the armoring outfit and designers for keeping THIS superhero close design-wise to its comic book origins! I was really impressed by how authentic the armors came out and by the fact that the design crew RESPECTED the original armors and incorporated the best ideas instead of ignoring everything like just about ever other superhero film has.
