For modelling the ear I had a problem and that was my hair in the photo had covered half of my ear. I could not make out parts for the ear so I had to guess where my ear was.
I modelled the ear by using similar techniques to the face. Drawing the topography in Photoshop then creating quadrants in 3dsMax which were then repositioned.
For the ear canal, I used the Chamfer tool which created a ring of edges that could then be pushed in to create a void.
After I had attached the ear to the head I then made the eyes by using spheres and then added an eye material.
