Creation, destruction
Animation was very good, original, I loved it.
But the message at the end, unfortunately, I fond to be off. Destruction is but another form of creation, simplifying something into a more basic version of itself until it is something completely different than it once was, or at least to make it occupy less space.
A better moral/message would be to create and destroy in moderation, as if we create too much, there won't be room for anybody elses creations, but if we destroy too much, then we'll have nothing to create with.
