Commissions are great when I'm not directed. One time a woman wanted me to paint a design exactly like the one she took a photo of in the department store. The commission you've made is all you, like if someone told you to paint the sky, as @jompiy would.
Looking forward to the old Irish flag.
I like commissions that give a starting point. When they tell you the result they want, we can always redirect them to AI. Or in Stuckism manifesto speak: "We only denounce commissions that stop at the starting point — Black Ivory start at the stopping point!"
