Well, it looks strange for a couple of reasons. First of all, your perspective is off a bit; the figure in the foreground should be a bit larger. Second, as the sun is overhead, you should not have that shadow cast right and forward away from the figure. Third, the focus doesn't match in terms of depth of field...the figure in the front is not sharp enough; was the image of the man in foreground shot with a different device than the rest?
