Pretty nice. It is hard to create strong image like this with such a symmetrical composition.
Simplicity of the lines, wide belt of water , symmetrical belt of mountain and equally wide belt of clouds.
On top of that the sailing boat right in the center.
I do not think you have planned it, or studied a lot the rules of composition in art and photography because this photograph is exactly what all the teachers tell not to do.
It came out very nice and interesting.
