Interesting rock carvings. I feel like perhaps the shot would be more interesting or appealing if it were taken from a different angle so that there would be more color behind the figures. Perhaps a shot from lower, rather than higher? It may just be that the surrounding environment doesn't allow for a truly unique background opportunity :-)
Pretty neat shot. Carvings are clear and focused. I might have adjusted the shadows level up a bit to bring out just a little more detail in the faces. For myself I would have chosen a portrait crop for this situation. Using the thirds rule, I would have the taller statue in the left third, smaller on in the center and negative space (water) in the right third.
