Head/Face mesh

Here is my completed character mesh.

 

I tried to make the edges flow as smoothly as possible and for the most part I think it is ok aside from the area just under the nose.

I decided to simply make the beard by extruding the faces where I wanted it and applying a new material to that.

The eyebrows are combined with the main head shape so that the blendshapes are easier to create and actually deform with the rest of the face when it moves (if they need to). The eye blink will also be a blendshape where I scale down the inner most ring of the eye until the two parts meet.
