Also Ed's face gets a bit of the old QUALITY in quite a few cuts
Strange, I did not notice any.
It's constantly fluctuating from highly detailed to distant figures that are only slightly more detailed than stick-figures.
I don't really get where you're coming from but loss of detail is to be expected during animation. It's why the character are so much more simple compared to the backgrounds. Take even Miyazaki's film, which are obsessively "on model" (they go through a lot of check-ups and cleaning) and still, compare the backgrounds with the characters and the difference is obvious. Or look at any shot with background animation. The loss of detail is pretty much a necessity because few (if any, not even Ohira Shin'ya is that obsessed with detail) animators are insane enough to run themselves dry, redrawing small increments of the same picture over, and over, and over again.
And then, some movements feature very distorted bodies because they portray a very stylized motion. Hands in the air, the torso becoming a weirdly shaped blob during fast rotations etc. It does not matter how these individual frames look by themselves as much as it matters how they look in sequence, how the motion ends up being portrayed through animation.
