I don't know what to say. The colours are muted, the composition is simple and straight-forward, there's no story or characters or architecture.... And yet it blows my mind. I guess you just capture the sizes and distances zo well!
You've got your own style of mesas, I like it. It's between the shape of a peak and the shape of a dungeon. Really effective to build an architectural-though-natural landscape. And again, great sky!
And again, great sky!
