Hey, thanks, I'm glad you liked it!
Yeah, nothing I can really do about the elbows right now unfortunately. That may change when I overhaul all of my graphical stuff some time in the first half of next year when I build a new PC though.
Pubic hair is probably not gonna happen, sorry! More medium sized chests are definitely coming down the line eventually, however. When I first made all of the main girls I deliberately made a range going from small to large, however it just so happened that the two smallest (Akatsuki/Sarah) and the two biggest (Lucy/Vicky) got all of the early attention.
