Improvement is need badly I can't really say much because it looks like noting was pretty much done. I noticed on the right side of the sig I see a line where the pyro is going off.
If I'm looking at this correct you slapped the render on it first, then got that image and copied it a few times and used the blur tool or one of the many blur effects, Then slipped the text onto it.
The left part of the sig is naked and needs some loving.
One suggestion I can offer is that tut site I showed you. ;3
