So... decades ago the original publishers of "The Shield" sued Marvel Comics because the shield Captain America used back then looked too much like the costume The Shield wore then, resulting in his now-iconic disc shield. But now, The Shield, named so because he originally looked ridiculously like a shield, looks a lot more like a Captain America knockoff than a shield. I've never read any of "The Shield" from back then so I can't comment on their similarities, but from what I hear Marvel basically ripped off his origin story. So going simply from looks here (of which this looks really good mind you), it looks like they're turning him into a rip-off of his (albeit more successful, influential, and popular) rip-off. But speaking solely of the art, this is ten times better than anything Rob Liefeld gave us with Cap. (That's meant as a compliment, because although he has numerous websites dedicated to how much he sucks, he was still one of the most popular go-to guys in comics at one time (even had a commercial about him), and considering how many titles he's taking over at DC, it would seem he still is, and I'm saying you're better than him as an artist.)
The Shield is the name of several fictional patriotic superheroes created by MLJ (now known as Archie Comics). The Shield has the distinction of being one of the first superheroes with a costume based upon the United States flag, appearing fourteen months before Captain America.

What I think? Well, I think you're awesome at what you're doing and you should make HUGE money out of this talent. Nope, I can't offer you a job but I just want you to know that I'm amazed at how cool your renderings are.
