Guess I'll join the others before me in voicing how much I really, really don't like a lot of the new changes to the way the girls look. For me personally, most of the changes are either meh or are huge downgrades from the way looked before. Its to the point where some are just straight up ugly to me now.
Of the main girls:
Annie: Her changes appear to be fairly minor and is one of the few the I have no real opinion on one way or the other.
Chastity: A MASSIVE downgrade for me. Like yikes. She doesn't look anywhere near as good as she used to. If I didn't know any better, I'd swear I was looking at a different character. Everything about her new face is a huge miss for me and if this is how she's going to look going forward, I've lost all interest in her character
Chloe: I'm not all caught up in the story so I'm not sure if there's a narrative reason for her change but I'm not a fan of the changes to her eyes in particular. Her changes aren't as bad as some of the others but it still bugs me.
Emma: Emma was very cute before but now, it's like her forehead swelled in size or maybe her eyes are lower on her face now. Either way, the charm she had is gone now. In a word, she sort of looks like a moeblob now.
Gwen: While I don't hate her face changes, her hairstyle is what irks me. Never been a fan of twintails, especially not short twin tails. Also, maybe it's the artstyle shift. but even her head looks significantly larger now. Weirds me out a bit.
Jessica/Kana: No real opinion on. Her changes appear fairly minor.
Lily: Here's one where I actually don't mind the changes here barring an additional tweak or two here and there. With a bit more polish, I could come to actually enjoy her new look.
Luna: This is another where its a straight downgrade for me. Whereas before Luna was something of a monstergirl in my eyes, now she's inching more towards furryville and while everyone has their kinks (to each thier own and all), this is DEFINITELY not one of mine. Her previous look had this mysterious sex appeal to it. This new one? I have no interest in knowing more about her or even being awarre she exists.
Lyx: Personal bias here, but for me long hair > short hair every time. The loss of Lyx's ponytail is a big blow for me. That's really my only issue.
Madison: Her new facial structure has lost all of its sexy teacher appeal that it had before. Now she's sort of...generic? Her charm has been lost and I swear her cup size went up a few times. There comes a point where brests can get too big to still be appealing and I think her previous measurements suited her just fine.
Morgana: I did not care much for her previous look and this is no better or worse. I still think it looks bad, but no worse than she did before.
Qarinah: I...don't hate this new look, but I still liked her previous one more. I dunno. This isn't bad per say, just different in a away that saddens me a bit.
That's all I've got for now. I haven't seen much of the side characters so I can't give my opinion on them yet. Here's hoping that some polish goes into brushing up the girl's looks. I get that for potential legal reasons they needed to be changed, but man do a lot of them need more time in the oven.
