It’s time to fill in the cheeks. First I extruded the edges around the edges of the mouth and the beginnings of the nose.
Then I started to create the lower jaw by extruding an edge by the bottom of the mouth, at the edge of the chin.
I stopped the jawline just before and above the ear, and began extruding the edges forward to begin moulding the cheekbones.
The next thing I did was perform a radial extrusion on the bottom edges of the eyes. This would create the front of the cheekbones. I then merged the eye to the nose.
