This is awesome. Poking around I saw the progress pictures on cghub, which I really enjoyed too. I thought your raw render was pretty amazing, and then they just got better.
If you ever feel the urge, you should poke over to the 405th. The existing pepakura model for the Scanner helmet has some funny proportions. And by one method or another, I know I want to make one of these helmets I can wear.
If nothing else you've helped me get a few more reference pics
This is one of my most used helmets in-game. Next to the stalker helmet of course! But the sheer amount of detail you put into this is amazing! All the praise you've received, you have more than earned it!
