There's this art-thief I've had to keep an eye on for a while now because she keeps "borrowing" the artwork of Sangheili artists, or just making blatant trace knock-offs and passing it off as their own work. She usually goes by the name of "Grunt-Arbiter" or "Grunt-Arbiter-Hanna", or some variation.
Oh that is beautiful! She does look like a high priestess indeed, the ceremonial cloak or robe, whatever you'd call it, looks absolutely amazing! I love the figures on the sleeves, I immediately thought of ancient Greek paintings.
