Catherine Lachepelle:

Multiples frames where only the lips move and nothing else - you should try to ALWAYS keep a slight movement in the body. There is also a lot of twinned poses (both sides of the body doing the same thing at the time) which you usually want to avoid

Robert Cartwright:

Love the emotions! The animation poses look really great! I'd maybe tweak the eyes towards the end on the second character, they look a little too closed, more like he's tired than frustrated. Great work!

Gabriel Mira de Assumpção Peixoto:

The poses need more holds and inbetweens, ant the characters have no expressions on them.
