Richard Clark:

Haha! Funny setup!

However, it lacks the fundamentals. Just simply moving the mouth and eyes, for the most part, doesn't gain interest. Even though your posing is good, I would venture into body mechanics like you started at the end with the male character.

I would also suggest learning the simple "bouncing ball" exercise to start understanding the basics of animation.

Paul Lange:

I like the character designs.

Jessica Matson:

The character designs are awesome! Something to help beef up your animation would be some more tweening and movement of the bodies. The characters feel very stagnant at the moment.
