...the majority of the people are saying square. Do you want to make your art according to what the majority would do?
This was my take on the subject.
If you are wanting to use the image to please others, (selling the image), I would consider square to potentially sell more.
If you are keeping it as a photo for your own personal gallery, (desktop background, etc.) then whatever you want.
For my taste, I would square it up. I rarely ever intentionally do an edit by going against what I think is right. Though I want more gigs in life, I have to stay true to myself so as to not get lost in the business stand point. With that, however you feel is the right answer.
Since you posted the square one first, and it looked great to my, square is where I think it should be.
