Wow, great! I love the style!
It was a bit hard to follow at first, until i read your comments and rewatched it to get the story line, but the first thing I thought was: I REALLY LOVE THE STYLE!!!
This animation also really struck home with it's theme for me; I feel the same way, and you conveyed it beautifully. Thank you. It's really inspiring :D
And may I congratulate you on the superb backgrounds - they're excellent. I usually feel that using bitmap backgrounds is a bit like 'cheating', but you managed to make them fit the style and added something magical to the flash. I especially loved the dancing girl's room, and the foggy bike ride to school. The only thing i feel needs changing is the character differentiation, because while the designs were nice, the fact that they all had the same hair colour made it confusing. It worked to express the common feelings of the characters, but it was hard to distinguish their individuality.
The overall effect was beyond my vocabulary to describe however. So I'll just say thank you again, for sharing this with us, and good luck on your next project, and achieving your dreams!!!^__^
