Text looks bad.
No sense of flow.
Colors don' really compliment or coordinate with each other.
The render looks LQ.
I advise looking at some tutorials, man. Get some tips and just experiment yourself.
Keep at it, bud, ^u^.
I agree with everything Joey said, but to add to the list the signature it's self is a tad to big for the render too much empty space and an Adequate light source would do wonders along with some depth.
Flow IS present but it's messy, try not to center your focal (if you'd like I'll link you a great tutorial that covers positioning). The darker background colours look cool but don't seem to work with the focal and the effects surrounding it imo.
I'll link my favourite tutorial in the morning as I'm on my iPod at the moment.
