Wow.. what a great eye for details. A magic shot, absolutely brilliant. Those "blue holes" seem to float in thin air because of the shadows. And in several ways this photo happens on different planes. The composition and the rich inclusion of the the three different basic shapes counterpoints it. And the clean limited color palette, with a strong contrast and surprising color intensity. You really caught it all here.. embracing the maths of a good shot. This is one of those rare photos equivalent to an exclamation mark, one of the joyous instances where photo becomes pure art. Just perfect. And the more I look at this, the better it gets! It matches the theme like a glove. I really could go on and on about this one.. "Nice work", as they say.
