I know the feeling! My brain has a hard time understanding how some people can even suss that out in their head, haha. Arifumi Imai so fun to watch, he even infuses the simpler stuff he’s done with so much energy.
To be honest, it’s as inspiring as it is intimidating, if that makes sense. Just have to remember that everyone starts from the same place with this kind of thing. As you said, strong foundations like anatomy are key, and they also make progressing later on much less painful.
Was poking around on sakugabooru tonight looking into some shows I’ve enjoyed over the years and hoping to find credits for nothing specific, and I came across Shukou Murase. Michiko to hachin, Gundam Unicorn, Ergo Proxy, lots of great stuff with her name on it and a lot of it is really nice character stuff. In particular, I love the scenes with Audrey and the old man from Unicorn. This one especially.
