Great work!
I'm not sure if you mean it literally when you say "the style of humor i invented" or "animation style i created." Both the "humor" and animation style are not original. They may be seen less than other styles, but unless you're a lot older than you say you are, you didn't invent them. Albeit, your project isn't unoriginal.
Apart from that, which has nothing to do with my score, I found it to be very enjoyable. You did a fantastic job with the animation and perspectives - really a pleasure to watch. I'm usually a fan of dark humor but I didn't see any. The scene that came closest to having it was with the main character vomiting on the road kill (human sized hamster), which could be funny on it's own, but isn't in context with the rest of the very serious short. Without the humor, it's pretty dry. That's not a big deal, seeing as humor is personal opinion and others seem to think it's funny. I enjoyed concentrating on the art and animation.
Good luck. Hope your teacher gives you a critique with some helpful advice.
