[Update 2]
I have made the newborn and the baby head and i also have done a new test ani, again the timing is not right and the eyes are missing because the whole ani thing is not easy to do in zbrush. Anyway here is the ani, its very fast but you can use the timeline contol to get slower through it.

In the final ani, i will probably let the neck fade to transparent so the shoulders are not visible and i will need to get the animation a lot smoother.

I changed a lot on the eyes but also changed some other things a bit to make the ageing more visible.
Im currently working on a quiet ambitious project. I want to make an animation that shows the ageing process from a new born baby to a ca 90 years old man. For that i sculpt the most important head ageing stages and then make a simple morphing animation with that. I dont know yet how detailed i will make it, but its definately a bit stylized and will be without hair.
The only reference i have about the ageing process are profile drawings, of a quiet a lot ageing stages, out of my hogarths anatomy book and this small photos: http://zonezero.com/magazine/essays/diegotime/time.html
