That's just ridiculous!
Not really, let's look at this.
Okay, first I'll say this, All the red in the shoulders does manage to put more focus on the chest and shoulder area, and hides the near lack of design below. That said, the collar looks too formal. It might work better as a mock-neck than with the current collar.
There's a lot of officer's "dress blue" quality to this, to use a military term. It's very formal. Supes' uni needs to have more of an "let's get to work" quality. Collar should be more open. The cape needs to look a little more like Supes is more a Roman or Greek commander out in the field than a nobleman in the capital, where's you really would need a cape/cloak for protection against the elements.
Still, there's not a lot that shouts "Superman." Classic Supes uni has a real quality that he's willing to get physical. There's not a lot intimidating with this one.
