Lol, I saw the pictures before I read your post and the first thing I thought was "Holy crap, that guy is skinny!" Realized a bout 2 seconds later that it was a mannequin.
As for critiques, your left shoulder bell looks like it could use some more smoothing in the recessed area. That, along with making sure that the neckseal actually goes all the way up to your helmet, is all I can see that needs fixing. Lookin' real good so far!
