Very impressive I like this method. Thanks so very much for sharing. 
Interesting, I have done this with things like flowers, and musical instruments, but I hadn’t thought of trying it with a head. Maybe I will give it a shot. It seems to work well for you! 
great tut man… thanx a lot for sharing this.
actually, I used this method for 3D text and I planned to try head or whole figure also. well, you save my time 
thanx again. i prefer such cartoonish look.
