I am going to go against the already voiced opinion here and say "That is not a picture i would show people."
At a glance, here are a few things.
1 - It's not level, could be fixed easy enough thou
2 - The foreground is underexposed, unless you are going for total black, then that don't work either as you can still see it.
3 - Where is the sun? I see a lot of so called Sunset photos without the sun.
4 - It is "centered", rules of third.
5 - The sky isn't that interesting, too much of it, and too much foreground.
Overall i can see what you are trying to do, but the execution wasn't right.
