An ADI assistant was there keeping watch on Feral so nobody got handsy with him or broke anything. He'd mentioned that a lot of that statue is actually screen used, and that it is a suit. Didn't get exact details on how, but the little pieces like skulls and stuff, or the gauntlets could definitely pass as screen used.
My Q&A video is taking a long time to export and my computer keeps giving me errors. But when it's up I'll share the link here. I'll have all my b-roll I shots of the statue which shows off all the little details. The thing was so impressive!
They also took off the mask for me, which they say they don't do often. So you'll get to see the insides and all. It's one of the masks that light up like originally planned, but they'd said the light would only show up in complete darkness, so I don't have that to show off.
