Anatomy of the Face
As part of the Master Scientific Illustration program I wrote a thesis on facial expression. The first part of the thesis was all about the general anatomy of the face. I started off by making drawings of the skull from three different perspectives: the front, side and three-quarter view. All three drawings were made in pencil.
Reconstruction
The skull drawings I subsequently used to reconstruct the muscular anatomy. Starting with the deepest muscles, adding more and more superficial muscles on top in every layer.
