Hmm well there's a couple things I liked about it but a lot of things I particularly didn't.
First off, I like how the animation is smooth. I like the backgrounds, they look very traditionally-drawn and they're interesting. The colors you used were basic, but they popped out nicely and weren't in any way dull.
For what I didn't like, everything sort of went very out-of-proportion when the characters moved around. Obviously the style is very simple and needs work, however it doesn't look like it's SUPPOSED to look fantastic or anything, so it's not really an issue. But everything is just very messy and odd. Sometimes it looks like other characters are in a completely different spectrum compared to others in the same shot.
Voice acting wasn't so hot either, either practice mroe on that or get some actors. Some voices were better than others, though.
As far as plot and storytelling goes, there wasn't really a whole lot there, and I know it's supposed to be kinda random, but it was just very repetitive and unfunny to me. Overall, the whole thing wasn't horrible, but let's just say I was kinda glad when it was over.
Just practice some more and I'm pretty sure you'll make something pretty hilarious in the future.
