Well, i do have one or two suggestions...
1: make the sprites match the backgrounds. Final Fantasy sprites don't really go well with Mario RPG backgrounds.
2: ive the sprites some animation. All i saw was tweening. It takes very little effort to do that, and it's not very fun to watch. Animate the sprites a little.
3: Finish it BEFORE you submit it. It's completely pointless to submit a movie before it's finished. I mean, COMPLETELY pointless.
