Patience
That is the key for you when making flash. It seems that you rushed alot of it, or at least, didn't take the time to make everything looks really good. Example: in your first scene it shows sora walking at 90 miles an hour at a really choppy rate. Try to space out the steps so that it looks more natural, as well as draw in between those frames as well, to make it more smooth. Also when just drawing a character, just take your time, and things will turn out much nicer.
