This creature belongs to one of the sentient species in the fantasy setting I'm developing. They are called Sa'Jiir, and they can grow up to 3 meters tall, making them the most dangerous of the sentient species, with the only limitation of being cold-blooded.

The Sa'Jiir are generally nomadic, even if they sometimes live in human cities, and despite their menacing look they are actually quite peaceful. They are mostly traders (despite some small groups who survive pillaging around), who move between the northern and southern regions of the desert in caravans and trade in different goods.
They are also famous for making some of the finest and most colorful fabrics of the southern territories, together with high quality jewelry (gold in particular, since they believe it originated from fragments of the sun fallen on earth and it has therefore an almost spiritual value).
( The colour pattern is inspired by a lizard called Varanus Griseus, in case you are curious.)
