To be honest...
I don't know if this flash is worth finishing.
I have tons of suggestions that you may or may not want to hear, considering this is just some old project that you never wanted to finish. Just apply these suggestions to future flash projects rather than this one...
1. Make the intros way quicker and a little less graphic intensive.
2. Get less repetitive music, that shit got annoying as hell.
3. Work on your character design. I little less man-boobs would be nice. Also the wierd anime style doesn't match up with the beautiful backgrounds.
4. You need serious work on you're animating. Just making a bunch of body parts and tweening them ain't gonna cut it (unless it looks really good). Also that FBF at the end was pretty bad too, work on it.
That being said, the high points of the flash were the very nice detailed background and the rain and raindrops. All very well done.
