The top (from above the swan's head and up) would have worked as a landscape in its own right. The aspect ratio on this image is almost square, so there must be some more of the image which Andy has cropped. Whether the additional content leads to enhance or diminish the role of the swan is a question that Andy can address. Lightening the RGB channel's Shadows while darkening the Midtones and Highlights a tad, also brings out the swan.
