It's missing ... something. A boat? A bird? When splitting a single image up, try to make something interesting happen in each section so it tells a story or makes a comparison or something, as opposed to simply splitting the scene up.
Very pretty and serene. I think I would have made it more of a panaramic triptych though. Crop it just under that last big shadow and it automatically gains more character. Just below if you want the water to be the focus and just above the last shadow if you want the land to be the focus. Sorry it's long, I'm trying to be constructive instead of leaving just "nice job".
i like the colors a lot! BUT, BUT, BUT, your pic is missing a subject, the viewer's eye are looking all over the place without being able to focus on one point. 5
