this picture has pretty good balance and interesting composition (bias here, i love water, and a bit of rapids is even better!). I think you could have cropped it a little better, I would love to see a veritcally oriented version with about an 1/8th cropped on the left and a quarter cropped on the right. I won't hold that against you in your score, because I could be wrong (would have to see), just giving you an idea. I give you a 7
A little soft on the focus. I'm not sure if there was a better camera angle to get the near rapids and the bridge more centered. They sort of compete for your attention.
