Animation interesting,
The animation was above average I could say, however through the video I just heard grunts and moans, I mean the teacher could have at least talked about some random subject no body could ever follow instead of grunting a few times at the student. Also when the monster falls to it's death it could have made a less0human sounding grunt. A more terrifying one, though I'm not sure how you'd achieve that. The teacher thing could definitely be done.
Small things like this pull the over-all message together in a short story or at least improve quality of the film. Quality is after all what viewers want. Minor things such as this didn't bother me though I'd love this film even more had they been in.
I'll give you 10/10 because the concept was excellent.
