This is a concept art of a Anu'Dar male Zonizan citizen. Zonizans tend to wear usually red and black clothes, that are their sacred colours. Red represents the blood shed by Reka's tribe in order to unite the Ancient Tribes of Zoniza, and black symbolizes the skin of the Anu'Dar, the sacred race created by the Zonizans under the Gods' will, in order to rule the world.
Zonizan citizens, regardless their sex, give a lot of importance to hairstyles: the more complex and long they are, the more beautiful they will be considered. Males also tend to decorate their face with particular markings on their eyes and brows, like how can be seen in this artwork, in order to emphasize the "natural beauty" of what they believe is the perfect race. This Zonizan commoner wears a simple large-draped loincloth with a crossed sash made in a local oily wool called "Lik'Ban" ("dark wool" in Zonizan language) which is similar to the Earthling "Orbace" wool made in Sardinia.
The leather string he's wearing on his head is ornated by a decorative knot, which is a common decoration among Zonizan jewelry. The sandals, as well as the bracelets are made in hardened leather while the hair circlets are made in copper, a common metal in Zoniza.
