Looking good, though, one thing that stands out is that you may need to put the nose plug back in and then fill the seam line between it and the nose wall to make them one, if you know what I mean. How it is now, the nose wall is too thin.
I agree with Mac that it is more suited for a RotJ style helmet, but since you've chosen ANH we should try to guide you as best as possible with details from that helmet. Though, it would be unfair to say that it can ever be 100%, but we can help you make it troop-worthy!
Looking forward to seeing more. Though, the topic should probably be moved to the Work in Progress section.
