I think you should remove that white border around Strongbad. Then it would be pretty cool. Removing those is tricky - you need to do it frame by frame. I use Macromedia Fireworks for stuff like that. (That's how I made my currently incomplete "Goemon chased by a Metroid" avatar.)
im not very good at computers so i dont know how to do that. in fact im still working on how to get a sig image. maybe i shouldnt have used something that was intended as an aim buddy icon.
