anyway, i list down the things that to improve in that shot...
Horizon is slanted, need to align horizon.
There isn't any subject in contrast, for eg, focus on trees or clouds, these are merely to me background.. this pic is more like a snapshot than a planned shot.
Too much empty space on the top, would do better in 3:2 ratio for landscape shot.
Color is dull, need to work on enhancing the color.
