I see lots of shading heaped on iffy, inconsistent character designs and animation without much flow or elegance. As a proof of concept for his 5-tone-shading evangelism, it doesn't quite work. A lot of the scenes are cluttered with little that draws the eye. Some of the camera angles and framing just plain hurt. There's a lot of basic stuff that seems like it was ignored in favor of shading! and characters speaking Japanese.
I'm sure it took him a lot of work, and maybe it'll get him an animation job, so I guess that's something. Maybe with time and practice, he'll make something less focused on his pet interests and more on being a cohesive product.
