It's nice overall, but when scrolling on my monitor, and 'cropping' out the horizon, it becomes more interesting to me.
I vote the first one, I like the horizon line but I've never been one to crop a photo and I'm usually shooting at the widest focal length I've got.
Normally I would agree to crop below the horizon because the sky is so bland. But for some reason that I can't pinpoint, in this particular case I prefer #1 with the horizon in the frame. Maybe it's the colours. Nice shot.
