A bit more work on the sand texture.  This is the second layer of the process, it’s still wet in this photo and looks a little shiny.  Also a lot more color blending will be done in future steps…. but this gives you an idea which direction it’s going.

The real airport in Baghdad is just pure sand everywhere but I think I’m going to add a little bit of vegetation in a few areas just to break up line of sight to make gaming a little more interesting.
