First I tryed a few positions (!) on top of the scanner with my head being still, then I decided to move my face while the scanner was working but I was getting some distortion on the face texture until this last one. The effect on the neck was made first by pixelating with stronger vertical lines, then I applyed a plastic effect and finally I selected small parts of it and added a dabble and the ripple effect. I also used a sphere effect on the chin to open the lines and give it some depth.Hope this helps! 8)
