I like the play of colors going on in this photo, I like that my eye is drawn to the sun and then pulled back by the reflections of the colors of the sun in the water.  I also enjoy that this photo's location is extremely ambiguous, is it cold there, warm, what time of year and so on?  But that also let's me create a story for the photo in my mind which is really great as well.  As with the previous post the reflections created by the water cause there to be so much dimension within the photo for the eye to follow and create so much depth which makes it extremely visually pleasing.  The softness of the colors in this photo also draw my attention to this photo, the play between the lights and the darks, the colors and the shadows all create a visually interesting and pleasing photo to my eye.
