This is an awesome piece of animation you have here! I love the smoothness of it, the character, the art style, and the concept. I see this is your first submission and I hope it isn't your last!
The only problem is it ends a bit too abruptly. While the story is very simple, it would be nice to have a bit of a conclusion. He fails once... he fails twice... end? Just seems like SOMETHING is missing.
However, this must have taken you a ridiculously long time to make, so the short length is more than understandable. And despite my little criticism, this deserves nothing less than a 5 out of 5!
