Leading lines are those elements that ‘lead’ your eye to a particular part of an image.  In this case, the path and fence draw my eye toward the buildings.  The first building that I notice is the lighter stone building as the eye naturally goes to the brightest area of a photo first.  For me, however, there are enough bright areas in this image (building, white picket fence, clouds, frames of windows) for my eye to scan the whole scene and not focus on just one area.  This was a beautiful spot for photography!
