It’s a personal 3d project ,I had done in my free time , Its embodies my culture , my history,The Bedwin arabs . 
I started with sketch concept, which depend on the wars and invaders in the nabateans kingdome from the 4th century BC until it was annexed by the Roman Empire in106 AD. 
This war was invading by Herod the Great (roman client king) ,in that time the nabatians kingdom had a strongest civilians and warriors in desert . 
I tried to imagin how those bedouin warriors were in that period ,Tall, Strong ,they had Their special equipments. 

Those bedouins warriors have a mechanical machine on Their backs ,and what their duty is, when the enemy is attacking they stood their grounds guarding the border and turn on this machine to created cloud of dust in the border of the kingdom and struck down their enemies in the midst of the blinding storm .
