I began by extruding the upper edges of the eye, and then added a sphere with 18 subdivisions that would soon form the cranium. (also, in the following image you will see that I added more edge loops and cuts along the muscle beside the nose. I did this to help fix the issues of having so many triangles.)
It was also at this point that I mirrored the geometry and combined it. At this point I was able to add asymmetry to the face, making it more natural looking.
