Pretty cool, the end made me laugh. There's definitely a fair bit of room for improvement all around though. For starters, I'd really like to see you working on those backgrounds more. Making them more interesting, and maybe adding some motion to them to fit the hectic nature of everything else that's going on all around. Some of your characters are nice and fleshed out while some of the others ("some guy") are just lopsided stickies. I think more work on developing all of the characters would round out the whole animation, so it seems like the whole thing is on an equal level.
One thing that I think you did really well here though is the music! It sounds really good, the part with the boat is actually mastered pretty well, like the drums are coming through nicely and the bass is good and audible (and dirty!). It was a bit quiet there though, probably could have turned the post up a bit more. Also couldn't really tell what was being said at that part so I feel like I missed a joke.
Anyway, nice work. Keep going with these, I really do like them, and keep on improving :)
