I actually like the background and the colouring is all right on target. There are even some highlights near the bottom that give it a bit of depth; nice touch! All that remains is the blending of the render and the text. Considering how difficult text is to master (and I'm still generally bad with it) I'd just recommend you look into blending and get that all sorted first. For now, with the text, you could keep it smaller and stick with a plainer font and effects on it. What you have now I think looks a bit overdone so it doesn't match with the sig.
Oh and steer clear of Bevel & Emboss. It's a pet hate of many a graphic designer.
