Manipulation Animation

Here is another pencil test animation. The idea behind this animation is to manipulate the square in the middle of the shot. I've done this by making the square change it's surface properties several times. The principals of the animation remind me of Daniel Greave's 'Manipulation' but the actual style of my illustration looks fairly similar to 'Don Hertzfeldt's' work. The animation itself runs for twelve seconds and is made up of 130 frames running at 12fps. I think it's better than my previous pencil test work and I'm hoping I can further improve.
