Glorious
I've seen Wierd Al perform that live, all eleven and a half minutes of it, and I think you did it justice.
To begin with, you had such courage to commit to making such a long flash. That is the longest flash I've ever seen I'm sure. But your animation technique was perfectly fitting to the song in its exquisite zaniness, and that's somethiing I really want to stress. I've seen higher quality movies in terms of the animation quality (but that were shorter), but this sure was high quality for something that had to stretch on and on for eleven minutes. A lot of work I assume.
You have my ultimate respect.
