The Dark Crystal 1:1 Replica Mystic head

One of my favorite all time childhood movies was The Dark Crystal,so as I was having a chat with a friend he said I should sculpt  a Mystic and Skeksis.
I started on this the other day its a tinfoil armature covered in bondo and Ill be using super sculpey clay as I feel i can achieve the small swirl patterns the best with the polymer clay.
I have lots of reference including measurements from a screen used one so Im going to try and replicate it to the best of my ability.
I have about an hour into it but ran out of clay so I ordered more should be in this coming week.Here is what I have so far,its basically the rough out no details yet.
