First of all, I love what you did with the post processing. It has a nice amount of detail, and the colors work well together. But I would suggest a different crop, maybe just focus on a specific area of the picture as opposed to trying to get the entire scene in the photo. Maybe focus on the building and the rocks and sand below, or crop the other way and focus on the building and the man walking on the left side. I just think the building being right in the middle makes it loose some impact. Also, the horizon looks a bit crooked, like the scene is tilting to the left slightly, that's just a general thing I noticed right off the bat that I would fix. But other than that, very nice, soothing piece.
