That actually was pretty solid, you got a good grasp of animation and the writing of the characters really sells each of them and their issues. Especially as you can see X-RL7 getting more fed up with his situation.
The animation itself is pretty good for skeleton based, you got some subtleties there that I can appreciate. However I think the sprites themselves need some work. Colours are a bit too muddy, the bodies lack a bit of definition in shaping and the hair for most characters doesn't cover most of their head (especially noticeable on the women.) If you made the sprites more defined or even more detailed then you'd be making the most out of not needing to animate them conventionally but using the skeleton rig.
I'd also like to see what you can achieve by going full sprite with no skeleton, since you got a solid grasp of animation it would be amazing to see that.
