@NessIllustration A bit ago I wasn't doing much at all and I was still trying to decide if I even wanted to do that kind of work. So I did a book for a friend of a friend for $250 just to see if I actually liked doing it and to get some exposure to how the process worked. So to me the education was worth it because it really made me WANT to do more work in that area and find out that's something I like doing. Definitely considered abysmal pay lol but that was my choice.
I did negotiate 50% royalties on all sales though, just on the off chance it went nuts And I kind of took the drivers seat and had final say on all artistic decisions. But I figured if they can sell a few hundred copies that might be worth it.
