Your getting into a rut where you blur everything in the BG because you aren't confident in it. Well thats what im guessing atleast, you never did it before so i can't figur eout what else it'd be.

Stop blurring it. A bad or medio-core BG is better than an entirely blurred one.
The clipping masks is ruining the sig and the text. The blending isn't ad but it's nothign specail.

This sig just really doesn't stick out in the crowd. Its actually a bit dull.
