I don't really like the background it's too repetitive and looks...well like you simply duplicated it a lot. There are a bunch of foggy looking things over the render, and if you can get rid of those, they make it look sloppy. As far as the text goes, i would get rid of the scan lines and gradient, make it smaller and set it to a font like arial or veranda. It'll make it less noticeable and if you strategically place it in the sig it will blend in.

Sorry bud, if you need more help though just ask I'd be happy to show you 1 on 1.
