This has anime series written all over it.
Great submission. Two things bothered me though.
The graphics were okay but you could have made it much better if you had put in some overnighters for the details and some overall fine tuning. There were parts where it was hard to tell what was going on but I could see your style after watching it a few times through.
Although the sound was acceptible it could've used some voiceovers. I can understand why you would't though because the rest of the flash was great and the style in which you gave the story was great as well so voiceovers weren't neccesary and may of infringed on the rest of the experience.
Overall, you could either improve upon the graphics and the sound but I wouldn't change or tweak anything else.
