I'm an animator who also uses Maya.
Overall, this was pretty neat. The designs and textures were pretty good and the lighting was appropriate. If I had to offer a suggestion, it would be to add more subtle movements to the character animations. For example, when someone's head turns, what does the rest of their body do? You could add slight motion in each spine joint to make it feel more natural. Try not to leave a character completely still for any period of time; even the slightest idle motion will make it look better.
