This is my costume for this year. I made the mask portion from Instamorph and painted it over (the top part was a military helmet; I shaped the mask to fit it). The side rig was also made of Instamorph. The lights were done using Arduino. The armor was made from a foam mat, cut and shaped with heat. For the duster, I took an old coat we had lying around the house, dyed it, and added a rain cape on top of it.
