Lab Instructor? Does he understand topology? Side of the face does actually move, around the eyes etc and the cheeks. Okay granted not around the ears but look at the original mesh.

I didnt add any polys previously I merely improved their flow for a better deformation. Also having a better mesh will improve rendering as the render engine doesnt have to calculate awkward polys. Quads actually turn to tris at render time, so you can see my point of a cleaner mesh I hope.
