Again THERE IS NO NEW ART STYLE the specific artist you are complaining about is the very first one i hired 4 years ago and has been doing all the sprites and most of the sexual CG since, and the artist you seem to like the most joined our team over a year after that.So why the heck has the art style changed so many times? There are three art styles, although I think they've replaced almost all instances of the original art style by now. But the newer art added in the past ~6 months is different yet again and I really dislike it. They've even replaced some of the good art with it. Specifically, I've noticed in the bar when you buy drinks for one of the girls, that art has been replaced with the newest art style for all of the girls I've gotten to in my replay so far. I really hope they aren't replacing all of it with this newest style because I would honestly just stop playing forever. It's that bad.
I am sorry you don't like some pieces of art but your conclusions are wholly wrong.
