Interesting choice of selective desat. Not sure it works for me personally, although there are some aspects of it that I do like. If you had brought out all the browns and blueish-greens it might have had more appeal for me. Still, it is an interesting take.
Simple idea, executed with plenty of flair and skill. You've used composition and exposure very well to make such an interesting image out of an everyday scene that most of us might have overlooked. The water stream seems a little overprocessed, but it's effective anyway. 7
Excellent work. Had the shot been a slight bit sharper, I'd have said you would ribbon. Either way, one of the better submissions in this challenge. Good luck!
