Honestly, I've often described it as art barf. I do it all wrong. First thing I draw when making a person? The shoulder. I make a shoulder, which becomes the torso, then the head, then add arms, etc. It's so backwards and upside-down. Sometimes I'll have an idea, but like, today I just drew an axe, then I made a little topless stick figure chick swinging around a smaller version of it babbling japanese trochés. (kawaii desu baka waifu-ck you).
It's honestly just whatever strikes me at a given moment.
