Shooting for realistic head

CC welcome. Reference photos were blurry and I couldn’t use them as a UV image so I made the skin textures off someone’s procedurals here at blenderartists.org.

Still need hair and would love better lip textures if anyone wants to point me in a direction on how to get lips looking good from procedurals. I used a wood grain on these and they look really fake.
