This is a recent prosthetic make-up I've done at Uni on one of my classmates.
The make-up was sculpted over a lifecast of the college technician in Newplast Plasticine.

The appliance wasn't a great fit, but I manged to make it work, though around the mouth caused problems.
One of the guys in the college's photography dept took these photo's for me, I made some tweaks to colour in Photoshop.
