I find the image to show a good exposure on the primary elements along with a pleasing color harmony between them. Focus and DOF look to be good as best I can tell with the smaller image. The way you have composed the elements in the frame also works for me. The one area I would be inclined to deal with is the intense blue color of the upper regions of the water. While this may be what you actually see when diving, it is too intense IMO as I find that my eye wants to move to that upper right corner. I would desaturate that color somewhat to lessen its intensity. Note I am saying desaturate, not darken.

I was born in Indonesia with a Chinese ancestry. I am a businessman who is an avid scuba diver, adventure traveler, and someone who enjoys exploring the eclectic flavors of the food world.
Merging these activities with my love of photography, I am learning to create an array of photographs from under the sea to up on the land.
