What did sumerians look like?

They're supposed to have been Semitic right? They had a fairly regular supply of agriculture and meat from herding animals as well as from some hunting and trapping so I would guess that promotes a healthy strong physique. So does the labor, but the type of labor would also put a strain on the back and spinal column maybe. What about the hair, the skin, the eyes, etc. I'm reading the Epic of Gilgamesh for a research assignment in a Humanities class. I can't help but wonder what they looked like. The men and the women. They had prostitutes- it's mentioned even in Gilgamesh. Was there a major distinction of the appearance of the higher class women or more conservative women and the prostitutes? Were there standards or conservatism in appearance? Skin- Were they light? dark? Curly haired, straight haired? Black haired? Blond? Brown haired?
