The skull is made out of a polyresin (stone-based meterial), I then hand draw the design and use a dremel tool to carve out the design. Using the dremel to carve out the design gives it a very nice texture and over all custom look. After that has been done, I hand paint the design to finish it off. It usually takes around 2 days to complete a skull.
