I don't know what to say about this, it's really short, half of it is a credit reel, and the animation itself is really one loop and one tween. All of the starts I'm giving you are for that one little loop, which is nice, but very short. It's good, the proportions are flawless, and the movements are fluid and have perspective.
The only suggest I can make is to tackle larger projects when you're on break and can fully devote yourself to the task of making a several minute-long animation.
