|Greetings from the Critique Club!
Nice solid composition, love the solidity of the rock against the softness of the water. And the ripples in the water are great, they add some unexpected texture for such a long exposure.
Keeping in mind that landscapes and seascapes are always thick on the ground in FS, you have a lot of stiff competition. A long exposure and interesting feature to look at are a good start, but just not enough. The colours are somewhat muddy and uninteresting; if there ever was a shot that would probably benefit from desaturation, this would be it. If the colours are somewhat bland, then make the shot about the shapes and forms; a hit or two of contrast wouldn't hurt either.
Also consider easing up a little on the deep dof, esp when it's quite overcast and looks late in the day anyway. I feel that it adds to the murky cast to this pic.
Overall not a bad shot, just some technical adjustments and you'll be fine.
Hope this helps,
