I never really spent a lot of time sculpting in Blender and used sculpting only for corrective shapkeys.
This is a first complete head sculpt I made in Blender.
This is one I made long time ago but never really completed it.

A good strategy to perfecting heads is to start off sculpting the skull, then add the muscle, then the skin layer on top. You end up getting the most realistic heads sculpts that way and it trains the eye to see shape based around actual flesh and bone.
