Then draw the hand in a cuboid. Pay attention to the proportion of head and body when drawing (detailed in the comic book tutorial). You can also learn from mannequins, but the picture above is made by real people. If it's an animation, we should draw the legs longer (better looking).

If we look at it from one angle, we will be a tragedy, then don't say it.

Ps: I am a painter in Guizhou, and my age is 14. Nice to meet you.

Ps again: I will send a picture I drew.
