The animation

The buildings, environment in general seems more detailed than the characters in some shots. Some characters look weird and creepy while others make weird faces.

The difference between the ballet building shown at the end of the teaser and the characters shown so far is jarring (especially sloppy mistakes like the main character not casting a reflection on the floor despite the fact that the interior does), even the ballet shoes near the end seem to have more detail put into them.

Am I the only one who is bothered by this?
