I was geared up for a cat! How dare you! Anyway, the right side is cool, but the left side seems a little "lacking"
I like the added stuff on the left side, howeber, I still don't like the boxes, but it certainly can't take what you did to the other side with out getting to busy. The boxes just don't fit in with the other stuff in the sig.
I think that this is a pretty good sig. In my opinion, though, the right side has a few too many shapes added to it. The text also looks a bit weird over the scanlines. The style of the sig is nice though.
