Yeah, a signature attempt by me C&C.
I'd like tips on how I could improve.

Text placement is off and the focal is really dark-- this leads my eyes to the bright white text rather than the render, which should be the center of the piece. It also lacks flow (that is, the tag doesn't all go in on direction)-- try picking a render with some movement and following it, because this is all over the place. Also the lighting is a bit odd to me.

I kind of like the reflection on his visor but, I'll start a new one using your tips. Thanks.
