I like what you did with that helmet. Nice work on the alignment. Very subtle and natural.
Your version looks more like the cleaned up helmet that we know from starwarshelmets.com.
I think during filming the helmet was more heavily weathered.
I'm not much of a photographer but I thought these turned out ok if a bit blurry and overexposed XD
It's especially apparent this is a recast helmet on the ears. Very soft detail
