Fascinating statue - and I love the colors and the water-color-ish look of the background. The statue itself is a bit dark, though, the details indistinct. I would have liked to be able to see the stone of the faces more clearly.
Your focus and clarity are good. The photo does not have a lot of punch for me though. I'm not drawn in and kept there. It looks like you tried to get it centered, but in fact, it is off to the right a bit. the bckground is nice, however, there is a small roundish cloud to the upper left of the left face that is a white color, and stands out among the darker clouds creating a distraction. I like how the faces are silhouetted. Technically good. ~Heather~
Interesting idea and composition... I'd have liked the overall gamma a little higher though, with more shadow detail. Wonderful mood created by this shot.
