1 - First duplicated the base image and adjust the saturation. After duplicated again, I climbed a bit and put the image on the right, duplicated again to increase the proportion of sand, because I wanted to enlarge the bottom and side of the image, and stretched a little. I chose a clearer sky, I removed the background and the mountains of central stone using the clone stamp.
2 - Then I added the boat and dove, cut the corners of the image that I wanted, and did work with blends burn tool and dodge tool + for illumination. I used photo filter to give the final shade.
