Tutorial: Wound

I watched an online tutorial about how to create realistic looking wounds, I now have a slightly better understanding of how wounds are created and believe that with practice attempts, I could create a realistic wound of this nature. I can get all of the materials required (Foundation, liquid latex and paint) relatively cheap and as shown in the pictures, produces realistic wounds. For the more elaborate killings I will probably have to use different techniques (i.e. face stabbing etc,)
