Minor project: Developing Faces

It was time to work on the characters faces, keeping an eye on the influences (African masks, cubism), I am trying to incorporate the style into the features while keeping a realistic look to them.
Below is an updated influence map showing the style I am going for, specifically for faces.

These are still rough and need cleaning up and further development:

For the next post I will post sketches of different features which will be taken into Photoshop where I will doing different combinations to come up with satisfying designs.
