The suit looks awesome man! I've always loved the Iron man suit from the time the movie came out, but to be honest, there are quite a few reality checks in the abilty of the armor to be as flexable as Tony makes it look! (I don't mean to be naggy if thats the way it seems.)Anyway, the one that catches my eye the most is the shoulder area...How is your 'flexablilty there? In the video it looks like you can't move your arms upward by much...
On the higher note your work is truly remarkable, and I'd love to see the thing finished!
