Head practise for creating realtime character. Main focus was not on character design but on how to achieve good visual results on a natural character's look. e.g. what do I have to do, to get the eyes area right or how to do the hair?

The new Global Illumination feature of Marmoset Toolbag 3 really helped me a lot to achieve convincing realtime results.

I also tried some hair techniques Naughty Dog used in Uncharted 4. But I am still miles away from achieving this level of quality. (Can someone code me the shaders they used? Anyway I think I managed to approach a similar way in Toolbag.

Furthermore I made use of the Wikihuman Project Digital Emily 2.0, which gave me a great base to start my head textures. The hair, eyelashes and eyebrows were painted by hand or photo-edited in Photoshop. The eye models are also made by myself.
