This is a great subject, but its a little too straightforward for my tastes. I'd like to see it at a little bit of an alternative perspective. I think the biggest thing is is that it is taken from too close of a proximity. step back a little and find something that has some interest besides the water. Good thought, just a little bit plain for me.
this is a nice composition. It has a lot of texture to it! Very professionally done. Overall, however, the image seems to be lacking something to grab my attention. The lighting is perhaps a little flat, maybe if this was taken at sunset with more dramitic lighting coming in from an angle it would be a 10! -8 from me.
Good long exposure, like how the water isn't just on the middle of the shot, it's tumbling from the other rocks too. However, had you made this a little sharper it would have made everything stand out more.
How can I compete against this??? Wonderful composition with beautiful tones and contrast and technically so well done. I love the natural muted colors. You've really met the challenge well. Very well done.
