The Debbie art was exceptional, pretty much perfect apart from the odd extra finger lol. The Diane and Jenny art is also great, but one thing I've noticed is it doesn't capture their demeanor. Debbie has a sort of warm, motherly yet seductive look, which was captured in her art. But Diane and Jenny look quite emotionless and plain compared to how they are in game. Diane should be similar to Debbie, but more playful or cheeky. Jenny in game always looks either angry, smug, snide, or pouty.
Jenny also looks kind of younger or more athletic than she does in game. She's supposed to be 24 with a curvacious figure according to the wiki, but she looks more like a teenager with a slimmer body and smaller breasts and butt. Diane's lips also look a little too purple I think? To be fair the three of them all look quite similar in game, so some people might actually prefer the differences here?
I don't know anything about how AI art is made though, so I have no idea whether these things are intentional choices, or simply limitations with the AI? Either way it's great stuff, just some observations/criticisms for if you were looking for feedback.
