The more I see it the more I like and dislike your sig at the same time. I like that it's a sprite sig done in MS Paint, which I admire you for doing, but the porportions on some of the sprites seem wierd like make sure you're using the Stretch/Skew command and that the numbers are only multiples of 100% and that they are the same number. Anyway, enough ranting, 8/10.
Avatar: Either the sprite's wierd or the porportions are off again. I'm not going to say anything about the background or Paint's Gif protocol. 9/10
