I'll have to give credit where it is due: he's pretty fucking good at making 3D models look like 2D animation, far better than most people who try doing that. He could probably do some pretty good work on a cel-shaded video game. I'd go as far as to say that he does a better job than certain professional studios (though admittedly he had more free time to get all the lighting and whatnot right). I also like his colors, and some of his compositions look cool. However, it's pretty obvious that his 2D animation has a lot of issues (though significantly less noticeable in this video, since it's full of 3DCG), especially given that he's in his mid-30s and has been drawing and animating for a pretty long time.
Normally, I wouldn't be dissecting someone who's just making free cartoons for the Internet to such an extent. But Otaking is a special case. For years on end, he's been shamelessly trolling everyone with his 'superior animation taste' in order to become a controversial online figure and draw attention to his work. I think it's blatantly obvious that he doesn't truly believe a lot of his nonsensical ~ANIME EXPERT~ statements (especially given that he's contradicted himself in the past), but he does believe SOME of it, and it's getting in the way of his improvement as an animator. He wants to bring back the feeling of 80s OVAs and movies like Gunbuster and Wings of Honneamise, but he'll never do that because he doesn't understand the subtleties of good movement.
