tough call. if you balance it like already mentioned and crop it, you might lose part of the effect of having the empty space. And it looks questionable if it is cropable to that extent. Not sure have to see it.
I actually like the blue. I like the photos cool look. it doesn't have to look like a desert to me. Perhaps you could think about it, and make some changes but in premise, this works for me at least. The person stands out, but just enough.
