You pull of that whole simple style very well. I really enjoyed the fbf animation of the girl. My favorite was the guitarist fbf though, I was hoping there would be more of that.
Overall though, it was a really cool idea and this site needs some good music videos. The ones on here are mostly crap, but maybe good movies like this will inspire people to actually animate again, instead of making 2 days games.
Anyways, I enjoyed it, and I hope you make something again soon, because your style is pretty cool, and with a little inprovement in detail it will be great.
