I feel kind of silly for asking this in the first place and will probably delete this journal once I have a satisfactory answer, but here goes!
Lots of people on DA (heck, everywhere) sell works containing characters that don't belong to them. From novice artists to well-known professionals, I've seen galleries full of selling custom Pokemon/character plushies, or drawing fanart for conventions, which are then advertised as being available as prints at said conventions. This never struck me as, well... entirely legal? So what's the deal? Where's the line between "okay" and "you might get sued"? Or is everyone just taking a risk?
Thanks, I've been curious about this for awhile and don't want to make a wrong move. >>
