I don’t think it can be repeated too often: try to get at eye-level with your subjects when making a picture. This makes you (and the viewer) part of the animals world and less of a outside observer. And it also creates a nice clean background that you otherwise wouldn’t get.
For this picture I was the only one completely laying down on the beach with my camera just a little above the water. The low clouds and water nearly had the same colour, creating a bit an atmospheric image.
