not bad, in fact i like it... for real...
very promising stuff here...
first thing...
i had to spend a whole century downloading the whole song for a 30 sec animation, this is not good...Try to edit the song with only the part that u'll need for the animation, then u publish, or try using stream...
I liked the animation, very simple yet very nice...
try to refine your drawing a lil bit, and adding some "textures" and movement, the animation was quite hard, when i think it would be better something more smooth, yeah... try smoothing your brush or using some tween... ehhe, but keep up the hard work! c'ya
