Love the shadowy feeling of the piers, however, would crop out the grass and rock in the foreground. I think that would strengthen the monochromatic image you saw here.
The picture makes you feel like you should whisper! But I do agree with sfranzen... it would be awesome without the rock & grass...even though you'd have to cut part of the reflection/shadow of the dock. I think it would still work!
Nice texture & feeling of solitude!
