Ah, Colleen, I recall voting on this and looking at it multiple times. I find it interesting and artistic, but find myself wishing for one thing - that the beautiful lines in the top left extended down further. I was one of your 7's, by the way. It's nice to see a truly creative take on this challenge.
Simple, yet very effective subject for this challenge. Plenty of visual interest to hold the viewers attention. I can almost hear the sound of the water going over the lip. Well done!
