I can't tell what is in focus? Typically a photo needs a main subject that draws your attention and the rest of the photo complements it. Here the whole photo is screaming at me and I can't tell what it's trying to say.
great idea, interesting, but you need wither a faster shutter speed, to make the drops hang in frae perfectly still, or a slower shutter speed to make them flow (result is like sand or salt being poured). This is half way, and does neither.
I guess if I want to be challenge picky, there are spheres instead of circles in this picture. I like the creativness of this picture, though. The water from what I would assume to be a fountain makes for a nice effect. It would look cool to have the focus on the water instead.
