*An observation - Uncanny valley - hair looks fake where it is supposed to come out of the skin, perhaps you should taper the hair root tips otherwise it reminds me of a Bowl cut hairdo or attaching a fake mustache prop to an actor rather than seamless/gentle attached to the face.

Maybe an easy universal solution would be to add opacity/fade for the hair root from tip into your Digital Hair Shader so that if others bring any custom characters in, CC4 could help make their hair look good too.
