What in the world....? ;^) Interesting for sure. Stopping Action in the water spray I'm taking it? Wait, I see some mud being splashed...that's it. He-he. The green in the foreground looks a bit muted, like it could use some additional contrast. While this is fun to look at, it's almost like you don't know where to settle in with this image...so many different subjects to take in. JMO of course. Good luck in the challenge.
nice idea, but a little on the snap-shotty side. while this is a bit too busy to really get a feel for stopping the motion, the idea does look like it would have some potential, if you could have isolated one single subject getting wailed on.
The centered man is a little distracting, maybe trying another angle/being a little closer (or cropping) would enhance this photo in my opinion. Looks more like a snapshot to me. Just my opinion :)
