One problem
The only criticism I have is that with your style, and my lack of knowledge of all these Anime Series's, I find it very hard to tell female from male. I look at the faces of a lot of the characters and think female, then look down and realise they are male. I can't even tell if any of the characters in this flash are female. Other that that one problem, The Humour is Brilliant, the Animation is Brilliant, and the song is Brilliant. Very good work!
