This picture is beautiful and I just want to stare at it.  I like that there are three main colors that dominate the photo of white, blue, and grey.  The line of the pathway draws your eye out to the little white chapel were you eyes then follow the draw of the white color into the clounds. The chapel sets in the center placement of the grid and the horizon is nicely placed as well, not too high or low but easily at eye level drawing focus across the picture to offset the etreme desire to follow the stone path into the depths of the picture.
