This looks pretty nice. The BG is really dull so that's what I would work on the most. The text looks alright.. Render effect looks ok. I would just work on pimpin out the bg with b/c layers, gradient maps, and lighting.
Much better. A B/C layer is a brightness contrast layer. that way you can up the contrast on your sig which makes the lighting better. I would stick another one on there as of now (be sure not to overdo it though).It looks like you're getting your touch back though. Good job.
