Needs work

First off, no one likes sprite movies. Second, if you are going to make a sprite movie at least make it higher quality. Third, make it longer, give it a story, as well as music and sounds. Fourth, you would normally want to draw your own flash rather then using pre made sprites, sprites are for lazy people who cannot draw.

Oh I dont know

The style you made it its good. But this seems to me more like some sort of test than animation. Put some effort into improvement, add sounds, storyline or something and dont make it look so ordinary.

Good

Good but it needs some music and sounds and it should be longer...

Rough

It was good but i think you should have speed up the fps so it would be less choppy
