I like the idea of using hand drawn art in sigs, adds a whole other level to the game, however it seems as thought this image doesnt really fit the theme of the background. maybe blend it a little?
Lol crofty and his pixel borders. I think sometimes its good to mix it up a little bit, so well done.
I really like the animation as well, looks real good, the only thing i would change is that Its a little difficult to read your name.
All in all, real good lookin. 9/10. 10/10 after a couple minor changes.
