Hate to do this, but...
If you're starting out in flash, PLEASE, PLEASE practice coming up with your own characters and drawings. I can tell from this flash that you're still wet behind the ears, just invest time in becoming better at drawing your own stuff. People aren't going to want to watch sprite movies on TV or in movie theaters. In the time it'll take you to master sprite animation, you could have come up with your own original material, you're creating the story yourself anyway, at least give it a try, don't take the easy way out. It's not worth it, I don't care how much people like Alvin Earthworm's stuff on here, you'll never see it anywhere else but the net.
