Lew you just listed a reason for the hand to be there (compositional balance in opposing corners) and then said that there's no reason for it to be there?? Even in a narrative or portrait shot, the shapes being arranged pleasingly has importance. Photos aren't just stories, they are images that should also just feel pleasing usually regardless of content.
However, I still do take issue with the hand as well, but for a different reason -- he has something on his belt that he is messing with, but it's right in the middle of the fadeout, and you can't tell what it is. Which is frustrating and weird, and probably not in an intentional way. Especially since it looks sort of like a gun (probably a cellphone or something, but any hint at a gun draws a lot of mental attention!).
