Its my current sig, and avy. Its Raiden from Mortal Kombat, i took the colors from his lightening and blended it together a little bit. Brushed some of the background, took the original 420x120 and scaled it down into the middle of the original image adding a greyscale to the original and adding a 1px black border to the scaled image with a 2px faded outer glow.

EDIT: just made this avy out of boredom....

nice sig bro

Thanks. im currently working on one of Kurt Cobain to tribute him.
