This is hopefully what it will look like, on the top view it wont show much of the skull but just the hair, while the window will show the full skull more
Update. Had to shave down a few parts of the skull because it kept poking through, eventfully deciding to just turn it off (the skull) and work on it (the face, with references).
Spacemonkey you made my day dude. Wasn't too sold on the concept, but that looks excellant. Especially all the skulls/suggestions of skulls within the armour.
