Skeletal studies

I have a half-filled sketchbook of skeletal sketches.  They are part of the skills to improve drawing skills.  I have a few sketches done from skulls.  I would like to do some full skeletal sketches from life but that will have to wait till retirement from the regular job and then I can spend sometime at the Natural History Museums.  These are helpful in understanding the anatomy of the animals and people, plus they make for an interesting change and some variety in the sketches.
