Looks like it needs some gradients and some more detail thrown in there. Little too plain, and it kind of blends a little too much with his practice jersey color. DeAngelo text also looks different and doesn't fit in font-wise. Maybe mix up the font a little on just that text, the other isn't half bad.
I hate to be nit-picky butttttt this would be a lot better if the background wasn't taking over his shoulder on the left side of the sig. I like everything else about it.
