Ha ha !
Great !
That was a good idea and you realised it very well. The animations are really cool and fluids, and the drawing rocks. And even if it's a graphic effort more than everything, i must confess that the sounds are really bringing something powerful in this small movie. Those horrible screams are totally awesome.
The overall was really enjoyable and very funny, and the shortness of the vid makes it have something burlesque. The mix between real video and animation is one of the best i saw since roger rabbit.
Very good job.
