The idea here is nice, and the vertical flip and the underwater point of view (I hope I didn't misinterpret this) makes the photograph stand out from the dozens of "ripples in water, whoa" pictures out there. The colors are also pretty - especially the orange reflection in the water. I'd prefer you submitted the image to photomanipulations however, although I don't exactly know how much you have edited this one. Submitting the original shot in scraps might be a nice alternative.
Creative treatment, to turn it upside down, and the title is perfect. You were right to keep it out of the photomanipulation section; the adjustments you describe would not warrant that label, in my opinion (eg, you didn't turn the nut-shell into a UFO and add little green men in the windows...)
