The beginning sets a different mood then the one that's actually delivered. The story is okay and the jokes weren't bad (I might be influenced by a huge LOL at the penguin scene, though). The animation isn't spectacular, but seeing that you have a "schedule" for posting these, they look pretty functional and don't really get in the way of the storytelling. What DID,however, blow this one up was the misplaced shameless-self-promotion at the end. Wanna call more attention to your other videos? Do a custom loader. It's easy and, albeit not that "cool" to watch, it get's through without getting in the way of everything else.
IMHO, though, videos should get recognition on there own, rather than through propaganda.
