I actually like this signature quite alot. I tried some different stuff and tried to keep towards a grungy feel then added some random upside down and backward text with low opacity (not meant to read.. just something to give it something) and I tried to keep the signature well balanced in depth and contrast and well I think it turned out nice.
-edit-
It's been a couple months since I did anything graphical and I guess I've gotten a little rusty. One of my friends stated something about the sig that I didn't even notice or think about when designing it. I didn't give any lighting point to the signature. Like the lighting of the background doesn't go with the stock lighting.. there really is no lighting to the background really, just darkness. Hehe. I might try to fix this and post another version later, but either way I still liked the outcome already.
