This strangely reminds me of Grim Fandago, which makes it even funnier.
Either way, there was really only one thing that bothered me a lot, and that was the camera panning in the start. It felt choppy and disorienting. I'm by far not experienced in animation, but it looked like you did frame by frame panning, which can make things look laggy instead of smooth.
Other than that, it was pretty spot on. Humor was good, but animation was a bit stiff, which actually kind of helped the humor in a sunday morning cartoon-ish way. Music was heard before, but it fit in pretty good, so I can't really complain there. Appropiate length too.
