Flanca shader part 2 (face fixing)

I have done quite a fixing of the character’s face (including shader, model, and texture).

First version, it is done by Arnold toon shader in Maya.

Second version, the first trail on Pencil + 4. Shading on both hair and face does not look good.

Third version. I adjusted the shader and texture of the face.

Final version. I found a free reference model online and learnt some technique to improve the look of the face.

Other angles:

One modification I made is to copy normal from a spherified face to the face of model. It can erase the physically correct shadow on face. Which makes the model look less realistic and more in anime style. 

Another modification is the artifacts on face, such as the shadow, lip stroke blocking and other facial expression related artifacts.
