The artist definitely has a type.
I like that there's a woman with the cliche "anime mom hairstyle" this time.
Also it seems the new game will have that setting where the protagonist has a government-issued license to have sex with anyone he wants and uses it to coerce the girls (at first, after the first fuck it's the usual Miel stuff) instead of trickery and rape. I'm not as big a fan of that, but at least it's not a full-on repeat of this game.
I think they wanted to avoid teachers or anything school-related for that reason as well.
