The animation here is good, but I find the progression to be a bit weird. For example, near the end, the little guy falls off of the table in one scene, but he's back on the table in the next? I also don't think it's made clear enough from the beginning that the end goal is for all of their shadows to be the same size.
All in all, a good start (especially with art style), but a lot of improvements could be made.
