Dang, another great cartoon! I don't think you could surpass that. It really is mostly action. The artwork is what really sells it. You have a good amount of character development here. As expected, that's hard to do in a single short.
Even the tiny details are great. I love the caterpillar at 3:13. It's just a very cute touch. I can see why this is at the top of the page. This definitely has the potential to be a series.
