Good basics

It's good that you are keyframe animating, it takes a lot more effort and patience and generally pays off BUT just now you're lacking the basics, have a look around for any guides on the 12 Basic Principles of Animation and try to practice and learn from them.

You could have tried a bit harder with the message bits, actually design the lettering, lay it out neater and, as someone mentioned before, show it longer. Rather than it just being writing it could add to the overall animation.

Pro-fo-sho

Definitely some of the most professional stuff on this site, it actually looks, sounds and is funny enough to be something I could easily see appearing on an Adult Swim block. Good job, hope to see more.

Superb

That was one brilliant. Very cool/stylised animation and the many jokes worked. Not sure about the pretty random mario bros bits, they didn't really have a place in it but apart from that, amazing work!

Wow

That was really good, nice art and overall great bit of work. Really enjoyed your music too definitely added to the experience.

Bee Eee Ay

As in BEAutiful game, really love how its looks the dirty watercolour/ink look is fantastic. The game has a lot of charm to it too.
