Rather than sketch out or take photos myself for reference, I used the supplied reference images our instructor!
I’ve got a few ideas in mind for what I’m going to do in the final render, but so far, I have this. I think the shape is getting there. The real fun stuff comes with materials and stuff. Let’s see if I can freak some people out with some photorealism 
Also I want to point out that, in some areas, those photos unfortunately don’t quite match. They are still great and useful, though!! 
Sorry in advance if you’re fed up of seeing your rendered head, Mike!
