I tried somethings more or less based on the Banu face, their shapes, colors. In a general exotic style, and some in a more human style (as we might want to be dressed like them, some of them would also want to be dressed like us!). The Banu faces are something bewteen Groot/tree shapes, and Beksinsky/bones style. So I worked around thoses ideas that I really love, of organics bones looks. (I tried the classic Moebius Arzack helmet, but even if it matched the vertical idea, the looks isn't enough relevant) ~sorry for my probably weird sounding english :x ~
