I didn't vote in this challenge since I guess I did not know what cool colors were lol. I see the "sharp" comment and I have to say that this looks perfect as it is. I feel like I am in the water with it. I love how the top (or head?) looks like a parasol.
I love watching these things. Used to own a coral reef tank with tons of shrimp, same translucent body, just fascinating. Some noise in the back on the deep blues detracts a hair from the shot.
Very cool all the way around. Beautiful image and gorgeous colors and light. Just seems a little noisy, especially in the lower half of the image, and the crop is a little too tight on the bottom. 8
