This is definitely the more "badass" version of the two.
That being said, there's a reason why Iron Man isn't colored like this: it's not flashy enough. And we all know that Tony's all about the flashy.
I like the design, might be the angle but I feel the chest is wider than say the movie version. If that was the purpose though than my b. It looks gooed either way and wider would make sense with it being armor.
