I've been thinking a lot on copyrights and stuff, these kinds of things really confuses me.
My question is, is it alright to sell the artwork that you drew of someone else's oc? Like if someone commission you to draw a painting of their OC, can you sell the original physical drawing of it for profit without asking or their permission? what about prints?
I see people selling their sketches of drawings done for commissioners to other people, is this OK?
