So my sci fi setting is not going to win any prizes for originality, it's a mash-up of Necromunda with Tatooine - a mining and processing facility on a red desert planet with an adobe aesthetic for the human workers' settlement. The human military forces are colonial marine types, and they can expect to go up against bugs (Wargames Atlantic Harvesters) and lizardmen (WA Lizardmen) as well as the odd Dalek.
What I've not got are some native humanoids. I'm thinking of Jawa and Tusken types, with flowing robes for keeping cool. Any suggestions?
