off balance...after much thought. There's nothing at any of the points of thirds other than the top 1/3 of the pic, which lies JUST NICE on the line. Thus making that area look nice and presentable.
you might argue that photography is subjective...well, i too thought so...but after looking through some street photographer's website...the rule of thirds still apply. What's subjective about photography is what you want to convey, but not the technique.
