My problem lies with how to communicate this to all potential commissioners in a way that will get through to them without coming off as a dick. I mean, I could just say, "no", but I try to be friendly and approachable to a fault. I just don't want to have to go through this whole spiel every time, and I'm not sure it warrants adding to my TOS.
I imagine it the same as a digital/traditional artist deciding they're not comfortable with x, y, and z subjects, so how do you all declare what you are and are not willing to do?
