Wow this is one if the famous crystal skull ,could this be the missing one my friend.Great looking piece of art work it is truly outstanding and love the crystal effect and light and the eyes you applied are amazing plus the wood framing of the stunner as well.
Being skeletal ain't so bad when you've got this kind of shine and metallic look...and how about those beautiful blue/green eyes...great manip, Rob...a very Merry Christmas and Happy New Year to you and yours.
