Foreground (flowers), subject (deb), background (Fence), Infinity (beyond the fence).   Also, the bride is framed visually within the arch of the arbor ... and there is a leading line on the right (the walk) into the image.  Very nice.

Again, lots of visual interest ... probably shot with the long lens from 40  - 50 feet away with available light.  The highlight on her side is beautiful.    Exposed for the shadow side of her face ... take the meter and face it from her face towards your camera.
