A Sangheili Officer who fights for the Thel 'Vadam (Arbiter). This is what I picture Arbiter's forces to appear as if they were to ever to walk through the new "Halo 4 Aesthetic retcon." I'm pretty happy with the results, I can also change the color so the Officer could become a Minor (blue)
I seriously hope the elites we saw in Halo 4 aren't just the "status quo" appearance of the elites in the new trilogy. I'd like to think that Jul 'Mdama's forces were given hand me down armor that didn't need Huragok keep up to work. While Thel's forces kept their armor from the previous Trilogy because the UNSC gave them Huragoks in good faith of their peace treaty.
I might just work on grunts, jackals, Hunters, and other previous covenant forces appearances of those aligned with Vadam.
