I am going to add to my scene by painting a few skulls. I am using the skull that is in the negative format. You can paint all of the features of this skull  or just use some of them. This one has some really mean looking eyes and serated teeth so I am going paint all of it's features. Again paint along the edge of the sheild allowing the overspray to drift onto the surface. Now that I have removed the sheild you can see how it has been painted. At this stage it still looks a little flat but don't worry we will add some more dimension to it in the next few steps. Now it's time to add the gum in this sucker! I am using the same skull that I used in the first one that we painted. Simply line it up with the teeth and lightly paint along the edge of the sheild on the top and bottom of the gum line.
