Good catch of the heron hunting in habitat, Stuart. Nice to see the legs through the water. The greens look a little oversaturated to me and I would try a version selectively desaturating them a little. Cloning out the vegetation that seems to extend from the tip of the bill may also be worth trying
I agree with Tony about the saturation of the greens. The background is a bit distracting and doesn´t help to isolate the bird. The head of the heron is croped at the reflection so I wonder if you have an uncroped version (in the case this image is a crop) with no cliping in the head.
