I'll be interested to see if this is 1:1 or just human lifesized. If you're going to get a piece like this it should be truly 1:1 and the sculpt should be more accurate IMO. Of course a 1:1 Na'vi would probably run in the $1,200 - $2K neighborhood.
Hair is all sculpted and Casey love painted the skin eyes and base , Eric O'NIel painted the necklace which are also sculpted, not sure if they can match the amazing paint job Casey did on the eyes
