I don't know your school, but you made me feel connected to it! Very well done.
I liked it, when the school got out of controle -even to an absurd- STEP BY STEP! Mostly when I see this kind of flash everythings normal and than suddenly without any warning is changing to pure confusion.
Also the music come nicely around with your animation. Great!
You just got 8 point because of partly bad quality of the pictures.
Oki doki, that's it for now.
