Hey Peter,
Thanks for your feedback! Actually yes, I am starting to work with axis lines and also lines that define the front and side plane of the head. For these last two, I have been doing division as suggested by Maughen of initially locating the eyes at the midpoint of the head, and then dividing by thirds from the hairline to define the brow and nose, and then one third down from the bottom of the nose for the lipline. All of those lines go to a vanishing point off the paper. All of those lines change depending on the horizon line which varies by model position either above or below eye level. I am still getting the hang of it all, but am finding it a very workable system of which, after some additional practice, I will no doubt understand better.
