Listening to Kristy Partridge on YouTube talking about why she doesn’t do art commissions. She hits the nail on the head in regards to how labor/time intensive private commissions can be. Actually drawing the art can end up being a fraction of the total time in some cases. I steer clear of them as much as possible as well.
