That is tough, i can sadly understand why you have to hire these Ai "artists" (call them clients instead) since it is true that hand drawn art is pretty costly and time consuming , while you are the one doing all the actual work with the coding / programing of the game . But you shouldn't settle for something less if you really wanna make something special that stands out , maybe you will learn a new skill in the process like how to draw yourself or at least have fun while trying.
With that said I guess i wish you the best of luck on your future projects (that maybe don't even need to have fetishes in them to be popular).
I will be looking forward to your work.
