Excellant work. The only observation I can make is that the amount of cables, wires, and hydraulics running from the shoulders to the head make it look more like the head of a robot than a helmet someone could wear. Still impressive, either way.
Thanks. You're right - I do not hidethat it is mirroring - it's a very quick way for symetricaly design, more funny, because I am always surprised by new shapes and expression of the "face" when I do mirror step. I thinkthat in case of suchdesignsitdoes not matter much.
