Lovely photos. I especially like the crisp bright look of Egyptian ones. It looks like real sunlight, is that what you used rather than lamps? A great effect, however you got it. Really looks like they're in a hot desert country.
Nice to see an all-Beja force, too, like they actually were. Too many of us fall to the temptation of mixing up our Beja tribesmen in an army with Ansar in Jibbahs, which I'm pretty sure never happened. It's understandable, because we want all the toys on our table, but historically it should be guys in white frocks or Fuzzy Wuzzies, rather than both together.
