actually, there is more than just that...
If a subject have a bridge, normally i prefer to see a full bridge, in this case, a panorama view would be great with the guy in 1 corner. The guy in silouette does depict some 'troubled' look, but not 'there' yet... perhaps if he tilt his head down would look really troubled. body gestures does help here.
anyway, composition not bad already...mine just treat as some misc extras... you could actually do layers to darken the shadows and also increase the dynamic range of the sky. but will take some time.
