Looking good. What i discoverd was that with the flatter flaceplate your nose get pretty squashed or you eyes get a longer distance to the eyes.
The original helmet is said to have eye ports bellow the eye sokets. They never looked out the eye sockets. It was like the Cylon helmets.
This also explains why the neck is so long. But again most of the armor we se is CGI. Very little of the Stunt versions armor were actually used in final scenes. They were also a bit bulkier.
Buy the book of Iron Man on how they made it. You will get allot of insight. And you be amazed.
