I think it would be better if you went back to your original image and transform in PS the central part of the image and then crop close to it taking out all of the top and sides. It would make it a stronger image if the superfluous top and side bits were removed and It would then become an interesting image?
Stamper, thanks for your suggestion. I was resistant because I like my photographs to have a sense of "place" and context. But I tried a quick crop on the uploaded image and it does makes it a much stronger image, I think.
