Awww. ..I think this is way, way underrated David. I love the idea of showing the movement. But I guess I won't try that seeing as how the voters sadly dismissed the idea, huh?
My eyes tend to go to the parts of the photo that aren't intentionally blurred (like the leg on the lower left). I like the effect of motion, but maybe more objects should be in focus.
I'm not sure that I'm a fan of the shutter speed on this one. It seems to be somewhere between the crisp action shot and a longer exposure to show movement, but personally, the exposure inbetween those two doesn't really work
Not sure if you were trying for the slow-motion impressionism. It's better than just being out of focus. But it doesn't quite work for me. Not my cup of tea. Interesting experiment though.
