I think these guys are right in saying more sky would have been cool, but this is a sweet shot nonetheless! So cool to see the stars like that. We have a completely different looking night sky in the UK (obviously), and it always interests me to see what people in other countries see at night. Really cool photo
Like others have said, I'm not personally a fan of the centered horizon, but it's not the centered horizon specifically that I don't like - it's the dark distant mountains that frame the horizon, coupled with the dark nearby rocks in the water, that give the image a certain visual weight that's just barely OFF-center. The bottom 20-25% of the image is basically empty space.
