Kirsten Schow:

The hand movements are kind of swimmy. From 200 to 220 the hand setting down on the table is very airy, almost like he's waving. Give the hand more purpose. :) I think he also needs some more eye blinks, makes him look like he's thinking harder about the question that was asked. Good job! Keep it up.

Ivan Mendoza:

The ups/downs of the mouth are good but you need more narrow/wide movements.

Ruben Uggla:

The movements themselves are actually pretty good, the expressions and mouth movements on the character makes him unfortunately appear very lifeless.

Zachary Checkeye:

I know it's a pain with a short amount of time but if you're going to have fingers, having them barely move or not move at all is going to be noticed.
