That is a satisfactory answer, thank you.
Anyway, like I said, Farm Girl for example doesn't need any new artwork. A few new lines of dialogue are enough here. Merchant Girl is broken... Only a repeatable scene can be added here. Wolf Girl, here are two options (concubine and dragon girl) and both would probably require some new artwork.
Anyway, now that I have your attention, I have one more question.
Isn't Issa an obvious candidate for warlock?
A chance to finally make him a real female!
