sorry
My unbiased opinion is that this is decent animation but the levels on the voices need balancing. Some are low some are high. Also maybe add some background noise or something more often. Most of the movie I could hear the gaps when audio tracks kicked on or off. I mean to say it was dead silence, because nothing was recorded to that space of video, then I heard a mic open up transmitting background pink noise and I knew something was about to say something before they did. Its a bit unsettling to make your viewers have forced precognition because they know a character will speak before they open their mouth.
My biased opinion is that all the characters in your movie should fall down a hole and die. Except teacher McBald. These people are horrible people.
