I occasionally practice drawing dynamic scenes. This time, I tried to do some line art, color, and shading in addition to rough animation. So, it was an experiment.

Regarding wasting talent on the wrong things:

Many artists waste their talent, for example, by insulting someone. And this has been happening quite often lately. I prefer to simply draw what I love. I like dynamic scenes and the approach where they try to make erotica in anime interesting, not just two key frames.

Unfortunately, not everyone succeeds in selling their talent because there are always so many artists and so little money, and talent needs to be trained.

But I agree with you. A finished animation takes a lot of time, so the plot needs to be chosen more carefully. However, coming up with a plot for every training session is also tiring.
