Thanks for fortuitous conditions.
This is a tough one as the reflection is so perfect that having the horizon at the approximate center of the frame gives a nice balanced feel to it. But is it too balanced thus static. I would suggest trying different compositions - more off top, more off bottom - to explore other possibilities. Pano crop too.
