It's a very nice signature. Very simple, and fitting colourscheme. I don't like Dusknoir that much, but it's a nice theme.
As for the banner, I don't really like the blending of render and background... It seems as if you did that with an eraser with hardness 0... Could have been better. =/
Also, maybe put the text in brown/yellow?

I fear my signature rating. 8D
