I hate to sound cruel but for a series, this is really all over the place and not very engaging to watch.
For one, you're using well-defined music from Futurama, not to mention character designs that look like characters from other shows (sven just looks like cartman from South Park).

Secondly, the pacing is REALLY slow and too drawn out. I would spend time trying to tighten things up. The main problem I see is that time is spent on things that don't matter so much - like the teacher's smoking. Try to focus on things that actually assist and push the story forward. While I understand that making short films, let alone series, is hard work - I'm tempted to think that not a lot of time was put into the pre-production of this. By that I mean, the idea was there but it wasn't given time to mature or sharpen up. You need to be able to see a really rough version of your film first in order to assess if it's paced well and reading clearly.

Thirdly, I wouldn't put the pause/note in the middle. At first I thought that was the end of the movie! Put it at the very end ;)

Sorry to sound cruel, but this needs a lot of work, and could stand to be much simpler/straight forward. Anyways, keep at it!

Peace,
