I have a tutorial series you can find on faemalia.net. Eventually I'll upload them here on ArtStation. These are the demo pics for that tutorial series, showing all the poses she should be able to make after done. It includes everything a nude female should have, including toes, breasts, midriff, back, and other areas that most tutorial series seem to skip when clothing covers up those parts of the body. Most notably, it covers shoulders and hips, which are extremely difficult to do when exposed.
The style of these images is the "composed image" in the centre, and four static camera views around the character on the sides. Those other four views I use to make sure that the joints/deforms look good from many angles, not merely the angle of the composition. Those compositions are not meant to be good, their only purpose is for understanding how the rig performs.
