I love the look. Very Kirby! Loki should have his horns though.
Why would anyone want more realistic looking armor for a Super Hero Comic about the Gods Movie? That kind of attitude is part of what damn near killed comics in the 90s. Besides, if one knows anything about the Norse mythology then one can see that Asgard and Valhalla are symbols of perfection. To me the armor fits that look and the Kirby aspect from the comics, as well. It's Midgard that's dark, grim and dirty. Why would the gods need to look that way?
Cosumes are good but far too shiny - they're looking very Iron Man gleam to them. I will be seeing this and all other movies forever in 2D - - I could not care less about the already tired gimmick of 3D movies.
