This is more a study for me, but hopefully it will be useful to everyone.
I’m building my portfolio so that I can apply for a job around Derby where I live, so if anyone has any suggestions, I’d greatly appreciate it 
Here I’m creating the skull in ZBrush, the female skull
It’s narrower, with a thinner cheek bone where the temporal and zygomatic meet:
The Jawbone is created out of ZSpheres, It’s more pointed than the male jaw (that squares off at the bottom)
In this, I’m creating the ribcage, scapula and collar bone.
Looking good so far.
