I like your photograph a lot. If you were to experiment with another crop option, you might try cropping from the bottom left with a locked aspect ratio. That would take a bit of the foreground out, leaving the sky intact, and move the columns off center a bit.
That being said, you might just keep it as you shot it. It is a very nice landscape.
