yow
I made a quick design sketch a while back and decided to try and model it. As always I took some liberties, so it’s not meant to be exactly the same.
c&c welcome

sweet… i have done a mask in the past as well… mine was a m-17 biological model though like the ones used in desert storm 
you can see it on my site if your interested
should be working on a riot cop soon - dont know if i will incorporate a mask or not - maybe just make a scene and use it as a prop.
keep pushing - this has promise
