This was honestly a bit of a failure on my part. It looks fine, but it suffers from a lot of problems, the main one being that I couldn't breathe in the mask. I did a lot of tests to make sure the mask would fit well, but I made the gross oversight of forgetting to test it on with a wig on my head. After I took it off after the con, I was severely dizzy and felt absolutely awful.
Plus side is I learned quite a lot while making this armor. It was all free-hand (as was almost everything I did by this point) and I used a lot of different methods such as undercutting and more advanced pattern making. The most interesting thing about this costume is probably the extra arms. They worked almost exactly as intended and I'm happy about that. I might revisit the "multiple arms" concept in the future.
