Cameron:

Good character animation, could use a little work on lipsynch, and the acting might be a little over-the-top.

Derek Stewart:

Nice render and expressions.. I just don't see much here in the way of appeal or premise. Good urgency and attitude though.

Craig P. Smith:

The characters tend to flop around a lot. You've come up with some good exaggeration, but the exaggeration should enhance the pose. Some of these look like they were done just for the sake of making it look cartoony or "animated". Even exaggeration should have purpose to the pose.
You also twin the arms in a few places. You could do with mixing up the timing a bit.

hamid:

too much tweening but good animation

Caelan:

Awsome. Just plain awsome

Joel Murphy:

Great lighting, and Great animation, but i wish what they were doing related to what they were saying somehow. I would have liked to see what the subject of their conversation was

Tina Tsou:

a tad too bouncy, but otherwise really good

???:

too much hands animation~

Britt:
