Simple Animation Practice

The above animation I out of inspiration by a blog that I came across a while ago; which I can no longer find. The idea is to do a simple 2d animation within an hour or so to work your skills and get better and better. This one being my first one, plus trying to do a lot of tricky perspective and camera movement took me maybe two hours. Overall I am pleased with it. It definitely hasn't been gone through with a fine tooth comb, but any suggestions or critiques are welcome!

Thanks, and happy animating
