Not too bad Awkword, just seems a bit oversharpened, actually alot oversharpened. Good use of lighting though, but some of it needs some work as well. I'd suggest working on your flow a bit, and depth. If you were to blur some of the deeper looking parts of this signature. Here's what I played with to give you an idea. I didn't do much except a bit of blurring on the background and a few gradient maps to create depth. Hope this helps you get an idea or two though. I have always found when someone gives advice and shows me an example using my work, I tend to learn a lot more than for them to tell me how to do it.
