Looking good so far Paul... The loops look like they're off to a good start, however, I'd suggest making one that goes from the chin around the face and across the forehead, and another one to define the jaw that ends up where the ear will be.
I'd also suggest pulling the forehead a bit forward making it a bit more vertival, unless your refs are like what you have now ofcourse
