Really nice head.

The only thing I dislike was that it is mirrored.

Datsick - Yes.
accer - If its all unmirroed will look to much random.

do u sell it? if yes - how much?

cartoon eyes in a semi realistic helmet? :S the face ruins the rest in my opinion and, instead of shading the plates as they were single pieces, try to add now a sort of global shading where you see where the light comes from
