Christian Stewart:

Try to get more movement in the other person when they talk.

Predrag Lazic:

The head turn feels a bit over articulated.

Ben Zingo:

pushing/exaggerating the guy's boredom/exasperation at the beginning would help motivate her turning around/reaction. Some really nice motion here though!
When she first turns around though, it feels a little stiff, like there should be some overshoot/settling after she whips around. Pointing directly at him, instead of upwards, might also help it feel more direct and aggressive
