I did a breakdown of a head in its most simpliest forms.

With this it should be possible to sculpt all kinds of the most common spicies.

I try to develope a technique for fursuit-head design with this. Maybe for 3D-Printing of heads :)

Want some big sharp cat ears, or long drangon angel ears? just pull on the blue circles... Done :)
Want a canine wolf-head? pull on the green yellow snout pieces... Done :)
Bigger eyes, or sad, more happy? Pull on the eye ring... Done :)

Well, some fine-tuning is allways needed, but this is a easy starting-base for sculpting :)
