I really like the movement you have in the water, and while the challenge description mentioned a moving subject, I dont feel that this is abstract. I do like the photo overall though.
I've been using the definition: "Of, relating to, or being a style of art in which natural objects are not represented realistically." I know that the water doesn't really look like that, but so many photographs do water this way that this seems much more realistic than abstract to me.
Very cool. Somewhat reminiscent of a Dutch photographer's work I handle named Karel van Wolferan. Check out our current show and I think you'll see what I mean: www.yuanfenart.com
