This is something that I've worked on, on and off, for a number of years. I found this skull outside of a storage facility in Miami when I was there renting a moving van. I held onto it for years before working on it. Originally I painted color onto the bone with a translucent psuedo-stained glass paint. I abandoned this and the skull sat on a shelf for about 12 years before I picked it up and completed the design I had in mind, in ink.
