Nice shot! Love the warm tones on the rocks contrasting nicely with the greens/blues. I think exposure could be bumped just a bit, but considering the dynamic range present, this is excellent.
add: The thumbnail looks like there is a person standing in the middle of a rushing river.
Cool idea, I just don't think it came across quite as well as you'd hoped. I think the exposure wasn't quite long enough and a polarizer would have helped with the lighting issues.
Beautiful flowing water shot. The orange colors in the bottom left have a luminescence that would be even more gorgeous if it was spread throughout the image. As it is, it seems to be an anachronism with the jumble of stuff to the top right of the image. 6
Beautiful shot. Its nice to see an image of running water that doesn't look over-neat imaged. I like the vibrant colors in the stream and you've seem to manage to shoot the wet rocks with superb crispness and clarity. Well done and good luck in this challenge. <8>
