As always it is a pleasure to see your work, the rock walls made me think about Jordan's Petra, the documentary I saw recently, where the city was built up in stone and also they created their pipe system in order to collect rain water and pump them up to higher level. You picture reflect warmth and it feels like it is also somewhere in sough where the rocks covered with dry vegetation and water is just recently collected, so in near future there may be some green plants will be covering rocks too. Like the way you paid attention to sunny side of rocks in left and the shadow on right, beautiful color choice too. Cheers, @Stef1
