Its been a slow and steady process to get this head happening. I have been moving house and starting new jobs through out. Lucky for me the company I am working for now has decided that I can have a "Blender Day" to improve my skills. So I have had the chance to begin work on the head topology. This image shows the first attempt. I have chosen a very simple method for building the head. The one described above by Joshua Alger is by far the simplest.
The ISSUU tute will be available soon. But to give you a sneak preview here's a screen capture.
