I think the new images are way better!
Just as most others before me already stated: the most important feature that needs improvement are the faces! Especially the face of Bunnygirl in the adventure/ story on the bottom left when she is talking. It looks weird and strange... As these are the first faces new players see - it's the most important! I don't want to dive deeper in the game if the first few images don't appeal to me.
Overall I really like the art style. I like that it's a bit "grimmier" or "dirty" (not in a dirty sex way but more like a dirty, grim world) and the tone is overall a bit harsher and harder then in HH. I think it#s a nice addition or change to HH. A couple cute/ waifu type heroines would be awesome but I don't think u need to go mainly cutish because that's already very present in HH.
But please change the faces! I already can asume that newer girls have better faces - but still... The main heroines of the story are the most prominent and you see them all the time. They need to be top-notch!
I would like to see divers bodytypes. Some abs, some softer tummys, some small boobs, natural ones, and so on.
Personally I don't really like the silikon-type boobs on Golden Silk and would have preferred to have her keep the normal tummy without those huge abs. And I really don't like Bunny Girls costume, but that's personal taste.
Overall I think it's a nice direction you are heading to but the #1 prio should be to improve the faces - especially those of the starter girls and the ones you angage early on - those are the selling point of the game that decide if players stay or leave.
