This is just one of those photos that shouldn't have been done as a centered composition. The photographer in the photo would be a lot stronger in the right third with your attention drawn then to the entire photo to see what he is shoot.
couldn't you have found a prettier model? Nice pic despite the subject. might have burned the windows a bit, plus the glow off GKs forehead. a little more contrast would be nice, but that's just my preference.
on another note...isn't he the cetre of attention enough? :)
