Pretty good.
It's pretty good for a sprite movie. A little tip; when you trace the sprites, go for 1-1 in pixels. Makes it look exacly as it's supposed to.
In case you traced it the way you did on purpose, I think you should try drawing (for example, the backgrounds) yourself. Or onion skin it. Would definitely make it look better.
Btw, I saw the trailer for this. ;)
