This photo gives a nice feeling. The composition really makes a statement - the darkness of the trees gives you a sense of the coming night. If I may make a suggestion, I think if the branches in the upper right corner were cropped out it would make the image even better
love the change in the water texture as we near the horizon. if it wasnt for that, we couldnt tell sky from water at all. the reflections are incredible. and the colors, stunning. glad you used that tree in the fg, it anchors the shot and creates a solid focus. the fact that it's a silhouette keeps us from having too much detail drawing our attention away from the beauty of the setting.
