|I think this photo is gorgeous. I can't speak for the rest of the voters (49th? wow...), but you got one of the only two 10s I placed in the competition. Colors are fantastic, depth is great, detail is tack sharp. I see now that you gave all of the light to the aperture... wise choice.
As far as the "thirds" thing is concerned, I think this image defines it. It's simple yet beautiful, elegant yet powerful. There's no question where we want to look, but you've kept detail in every part of the frame. Perhaps most impressive is that in an era of overmanipulation and postprocessing, you let the picture speak for itself. Great job.
