Salt marsh tree

I have tried to photograph this tree and the salt marsh several times --- in pre-dawn fog, on a cloudy sunset evening, and another clearer sunset using both a wide angle lens and my Lensbaby --- and have not really gotten an image I am satisfied with. This shot was taken on January 2, just as the sun broke through a cloud layer so I was able to get the reflection in the water. It is an interesting area and I plan on trying again.

Camera info: Nikon D200, 24 - 70 mm 2.8 lens at 48 mm, f6.3, 1/250th, ISO 100, cloudy white balance

Post processing: In ACR I added fill light to bring up the tree and the foreground, in PS I ran Kubota Luminizer, a levels adjustment for more brightness, a Hue/Sat adjustment for more blue in the sky, then painted with light and dark layers to bring out the detail in the granite boulders, and finally ran Kubota Edge for sharpening.
