I've had a giant Grifter sitting around for years, and finally found a skull that was the right size. Removed Grifter's head, had to sculpt up the neck since it was just a hollow space there, then sculpted the eyes, brows, and jawline, attached the head and painted it. It turned out really, I am happy with it, this one is for my personal collection. Also, I included a picture of my Red Skull Collection just for fun.
