You should try to polish the lip sync a little more on your next episode. Bigger contrasting mouth shapes and more variation. It was very flappy throughout. That and some small eye darts could help give the characters a lot more life during their long talking scenes.
Giving the characters expressions some more asymmetry could help them look a bit more appealing, too.
Keep up the good work! If you were the only animator pushing out that much footage, then my hat is off to you!
