Hi
It is interesting to see how many people like No.1
To me it confirms that a lot of people adore this sort of picture treatment. In the first image the sky/clouds start to look blocky.
I personally would go for No.2, it gives me a better feeling all round. In another thought, I would also pay attention to the horizon and level this so it does not fight my in-build spirit level I have in my head.
And I think a very light crop to lover the ceiling of the sky a little bit would give the picture a better aspect ratio, taking it more into a panorama look. And you won't miss this little bit of extra sky. The crop will be very small, but small crops sometimes make a big difference. Experiment with it and see for yourself.
Nice image by the way.
Greetings
