Hi guys,
here my last work:
for love of true I must say that I started my model with Makehuman and then I worked with Blender.
For lighting I used an image HDR and I played with rotation for achieve my result.
I remodelled the ear and re-sculpted all in Multiresolution; I changed settings for traslucent effect through the ear; I re-made the texture for the skin and I changed settings node.
Thank you for your criticism and improvements!
