I enjoyed it. I think the character designs and animations were very well done.
Here are a few comments...
The opening credits
It is fine giving people credit where it is due but I almost closed the movie because the credits were so long. I'd suggest moving them to the end or shorting them. The animation for them is interesting but I guess I'm not patient enough for them. It could just be me...
More important. Please give some love to the background. Add some props, lighting and decor. Right now you have a curving wall (floor) with a flat screen. Curve the screen also if you are going to make the floor curved. And last but not least, the characters all have outlines but the background did not. Equality.

Hi animation world.
