I haven't reviewed a movie in a long time. This is an all around great work. The color choices, fx, animation, even the 3D all fit together smoothly to create a beautifully rendered short. There are companies using teams of Flash animators to make television shows of lower quality than this. My advice is that you grab up someone to do your music. This series is going to take you somewhere and you don't need copyright issues slowing you down. Best of luck, man.
