I don't know if you have more characters planned or you're gonna stick with the current lineup for the time being and expand on those (which would make sense as well), but I'm hoping for more futa characters with a humanoid pingas, as animal ones are not really my thing as much. So right now Bluebell is the only one that really fits that category, unless I'm mistaken.
That said, I do enjoy basically everything in the game right now. As an artist myself I am usually not a big fan of AI generated art, but this is one of the few projects where the quality of the character writing is actually good (although the logic of why they need a human in the town is a little iffy lol), and it looks like you're at least putting in effort of trying to keep the images consistent and with a modicum of thought and effort put into them, so I don't mind it as much.
