The 5 pictures on the main link provided are the main in progress. I'm working on the tattered robes right now. I go the hood and torn fabric drapes finished. I should have most of the robes finished on Saturday. I'm picking up my black hakama that day and going to cut it up. The linked video is an old mask made of Air Hardening Clay. The clay version was too big and heavy, so I'm resorting to EVA Foam. Sadly I have a big head so the mask is proving a little tricky.
Where would I get a long sleeve black shirt with a turtle neck collar?
As for the chest piece what would you recommend? I'm using EVA Foam for that too because it's supposed to beaten and sliced up a bit, and is copper with a hint of dark silver, so I figured EVA would be best.
