Received this yesterday, 1:18th Predator trophy skull. I have 1:18th versions of all the skulls seen in Predator 2 (along with a few that weren't seen) except a decent alien/xenomorph. This new one looks like it might have been shrunk from the 1:12th version that was in the NECA trophy room diorama made available a few years ago, so I'm hoping that same person will shrink down the xeno skull as well. I bought this from a guy on Facebook, but I think he also works with a place called Demon Creations.
When I contacted him he said they were all available as of now. I thought about getting their xeno skull, but it doesn't look right for some reason. It reminds me of a xeno skull I used to see up on Ebay all the time that looked like it was sculpted by a drunk out of a lump of coal.
