Shadavion:

not bad

Cassian:

this has so much potential and a great amount of expressions! i also love the green guy and how expressive he is. i just think the female character is swinging her arms/ moving her body too much; i see you were trying to use that in a way to emphasise her words but i think she's doing it too often and it's a bit distracting. you don't need to move the character's body constantly when they're talking. but overall this is good :)
