This was actually a pretty good test!
The animation was fairly smooth and I was impressed with the quality of this madness animation. The only thing that I would really recommend is using a background that you made or simply a background that fits with the style.
Taking the picture and pasting it as the background wasn't the best of choices. It's fuzzy and really doesn't fit at all. It was rather short, even for a test, and would be nice to have some additional content. Perhaps moving on to a different section of town or some sort of transition?
The audio was very good and I have no complaints there at all.
