Yes carve out the eye holes, mouth area if you want exposed teeth, or gouge his head for injuries. Hot glue in the eyeballs and add fake teeth (using fake nails from dollar store). The first layer was toilet paper brushed on with liquid latex. Then we used the cotton balls dipped in liquid latex to sculpt in fleshy features, like brows, lips, etc. I also made some nernies to create the tendon/vein effect. I attached a YouTube video that shows how to make them, I think parts are in German, I just grabbed the first vid that came up on my search???
Allow to dry over night and then paint, we used acrylic craft paints. You can use stain as well. I think the base coat was a dark brown or grey, I added purple under eyes, in nose cavities, dark areas like that. The most important step IMO, is dry brushing, when he was all painted I dry brushed him with light tan, and a bit of green. The blood effects were added at the very end. He was really easy to make, I hope to make a few more for this season.
