You were like me when I started making movies...
Man! That wasn't a bad start! My first flash had the same quality too! But overall, Great first flash! I see you know some of the basics of the flash like streaming the sounds and music and you animated some parts by tweening and not frame by frame! ( I animated my 1rst flash by frame by frame, though).
Also, using sprites is an excellent way to learn how to animate well in flash, instead of crappy drawings or cool drawings that are really bad animated. =D
3 + 1 = 4/5
8 + 1 = 9/10
Note: I always give extra points at voting and review scores to 1rst flashes that are REALLY WELL ANIMATED!
Note 2: Take in mind that the only way to getting better... It's practicing by making and making flashes! And for every flash you make... more experience you get! =D
