Personal work I did using my old hair workflow in Blender before learning the new hair system. Sculpted in Zbrush, textured in Substance, and the rest is Blender.
OMG Dude this is insane! especially the hair. the skin looks like plastic skin to me tbh. Did you use a wig for hair? this is some of the most realistic hair I have ever seen in CG.
Here is the “Behind the Scenes” article of this incredible artwork!
Do check this article written by the artist himself. It describes the process of making the artwork step by step with an insight on making realistic hair in Blender.
