Well I didn´t vote in this challenge but sorry, if I did I probably would have given you a 4. Most of that is due to the composition and depth of field and the fact that I don´t really see how it ties in with the challenge by just looking at the photo, I needed to see the title to see where you were going with this and I don´t think you should need to do that, use the title to explain how a photo fits the challenge.
The reason why I say so is because of your choice of composition and placement of depth of field, my eye is drawn nowhere near the moving water but instead at that mountain in the backround and the clouds, wich are pretty nice. I almost want to say I feel like the out of focus water is just in the way of what could have been a lovely photo of that mountain, I tried putting my hand over the bottom 1/3 or up to the point the water starts to be in focus and well I thought the shot improved a whole lot when doing that. Also that black object in the lower right corner is something that is really distracting me, I would have moved to the left and taken another photo without it or if that was not an option, taken it out while doing the post processing.
If you really wanted to show a photo that emphasized the movement of water as rythm, I would have just concentrated on that, taking a more closeup of a wave and let the backround just be what it may, here I feel like the backround is the main focus of the picture.
One other thing, the haze in the backround, it´s not really crystal clear and I think you just simply took this during the wrong time of day, try when going out to take landscape photos to stay close to either sunset or sunrise, you will get much softer lighting and usually less haze, your photos will have much more creamy lighting and be more pleasant to look at.
I think it´s good that you are experimenting by going down low close to the surface of the water and playing around with depth of field, definately keep up the experimenting, that´s the best way to learn.
Nice shot! Would have liked to have seen more depth of color in the background, but the angle of the shot... and the shark in the bottom right :) ...is nice!
These rough waves look dangerously close to your camera! Is it a waterproof camera? Some sun would have been nice, but that couldn't be helped. The majestic mountains are overpowered by the wave action.
From the horizon up, this is a nice shot. Unfortunately what's below the horizon is the tie in to the challenge and there's some trouble there. Lots of overexposed spots on the waves, the big out of focus area in the foreground is disconcerting, and there's no strong presentation of wave like shapes themselves within the watery chaos. Do like those mountains though, and the sky is nicely captured as well.
