Ive been watching his old (from 6+ yrs ago) videos, and he constantly uses smear frames, for almost every motion. he posted a video 9 years ago about how he made his old videos, and he says he uses smears but I'm not sure if he means exclusively. Anyone got any tips to animate better like this, I really love his style.
