I like your shot, you did a nice job with the water but if I may offer a suggestion? An adjustment to the white balance in this image would correct the color cast and, to me, would show the beauty of the image much clearer. I hope you don't mind, but I have taken the liberty of downloading this image and doing some color correction in CS6 - used color balance and curves, but you can do the same thing with levels too - the color corrected image is posted here, see what you think. I offer these suggestions in the spirit of learning not criticism. Keep shooting, you do good work
