Your anatomy improved crazy fast! I absolutely love the vampire mesh and (sorry for being a pervert) the weird slited clitoris. Are your characters still going to be in the never nude gang?
It would also help to study anatomy and proportions. We have a ton of great resources, cached here: Anatomy Reference For example, PoseManiacs has excellent references https://www.posemaniacs.com/tools/viewer/poses/01H6RBJ01K4AJGPMCEYW5FKYFZ
