Looks great. How did you clean the skull?
I removed the skin and large chunks of flesh, then I dug a hole big enough to put the head in and left it uncovered for a couple days for flies and other stuff to get to it mostly flies so they could lay their eggs, then I covered it with a tin bucket and left it there for 2 weeks, when I uncovered it there was almost nothing left except connective tissues and some other stuff but mostly clean, then I pressure washed it, then I crawled around on my knees looking for teeth I knocked out while pressure washing. At this point it was clean but needed to be degreased so I filled the tin bucket with water and lots of dawn dish soap to but the grease, then I put an aquarium heater in the bucket to keep the water hot and to help with de-greasing. Left it in there for 2 days and it came out de-greased and pretty white. I never even bleached it.
