I've also been sculpting two 1/57 scale females: one static and one posed.
Today I sculpted the first layer of the standard 1/57 female (needs much tidying...):
...and again of the posed 1/57 female:
I'd have sculpted more of the latter but had an "armature malfunction"...
Here are my reference sketches for this pose:
The sketches were made from the book Art Models books. They feature a variety of poses captured from 4 angles (front, back and sides) and are accompanied by a CD with all poses (and more) covered in 360o. They've been really good for helping my understanding, but some of the poses are a little weird (or unfortunately obscured from angles by props...) and there could do with being more male references.
