This is it, the final part of the build. There was a lot of hand sewing, but it all came together nicely.
I broke my on/off switch, but was able to fix it myself. I should mention that I did not incorporate the vibration sensor. I had stated earlier that I could use it to shut down the animation of the NeoPixels. I had both the slow and the fast sensors and we tried both. We couldn't get them to activate simply by moving the mask. It takes quite a jolt to get them to activate and the mask is so massive that movements are not strong enough to trigger it.
