This is based on photo that I took a couple of years ago in the small village of Matmata in Tunisia. While this particular village has become quite popular and a sort of ethnographic show for tourists, the rest of the population in the area still has a very traditional way of life for real. Their houses are a kind of troglodyte dwellings with artificially made cave-like rooms dug around the perimeter of a large pit in the ground. Some part of Star Wars was shot in these dwellings.
I was surprised how much fun it was to paint the draped fabric of the clothing. Watercolor is perfect for that.
