The color scheme is solid but I think you should blend the render in more with the background. When we say "blend" we sometimes talk about smudging it along the sides and or adding other things to the sig so that it adds depth. The text does'nt have to be on an angle like your previous sig. In a situation like this the text might look good horizontal with the proper text glows etc.
I'm aware that your still a beginner and I'm not an expert by any means but I hope you take some of this advice.
