You could kind of list under the art that like
supposed "x" artist did it? That way you at least have a list and if an artists name is mentioned there and they happen to stop by the thread they could confirm whether or not they did/didn't do it, u feel me?
also I know for a fact #9 is done by iLalle, style is unmistakable
and I know #14 is done by Diadem (prev, Perfumate) too for the same reason
cannot go through and screenshot it because too many threads to search through
gl on ur quest m8
may u prevail victorious
