OK, c.g this is clearly one of your best sigs so far.
THe top right corner is very nice and it kinda adds a feeling to the signature, the combination of that and the grey in the middle of the sig create an ass kicking b.g, while the render is blurred to perfection and its visible but makes the viewer think.
I think that it is a great and different sig but people here aren't capable of appreaciating change, maybe make the text all grey but thats all i can say. You have overdone yourself.
Congratulations man and you should current it.
