I like the pose with that all important slight head turn. The exposure is spot on and the background is also very good.
There some pale patches slightly below the centre line, they don't trouble me but I suspect the image might be improved presentationally if they were to go.
What makes the image for me is the rising foot, very neat. Perfect head angle, great low perspective. I'd consider covering up the very dark areas above with a low-ish opacity clone tool (perhaps 30% or so) and to me it looks like the image needs some CW rotation based on the lines in the water. BTW, I love the brown and white plumage.
