Grey Fox costume Dev. part2

Someone was asking how I created my Grey Fox (Metal Gear Solid) costume found here

First picture shows the unpainted helmet with completed mask section. The separate mask is fixed in place with four very strong magnets fitted into the sides (roughly at my temples) of the helmet earlier on, and the "wings" of the mask.
The mask's structure is critical; size of the eye slots to allow peripheral vision and housing for the cyclops eye (seen picture 2) which IS a bicycle reflector. The mask is strengthened the same way as the helmet (made with metal mesh and masking tape and applied with thin layers of paper mache.
The third picture is comparing the shapes of the two helmets I'd made. The "bucket" helmet was 2 years before and was (in hindsight) awful! Made from paper mache over a balloon. The new one, seen in an early stage, having been built around my head, is much more elegant and streamlined.
