Graphically reasonable but lacking humour
Lets start with your animation: It's quite good, the expressions are done well, the drawn backgrounds are nice however your incorporation of various animated elements is crude, and it shows tha way - I'm not sure if that's a purposeful element of style, but for me it doesn't work. The contrast between well animated characters and some of the more crude animations just created an unfinished feel for me.
In terms of your humour, it wasn't really funny. The underlying comic factor was immature and didn't have enough scope to last a film of your length - and although there was potential for a funny parody the jokes made were highly typical and derivative. Ironic considering the genre is 'Comedy - Original' - a distinct lack of originality is seen.
Your animation has potential - polish up on your graphical weak points and discrepancies, then focus on building up your humour. If you just don't hit the spot I would prompt you to be an animator and let others focus on the script.
