Framing

This is an outstanding picture. Here you have the skyline in plain veiw, while the main focus, (the explosion on the towers) is perfectly places on one of the "thirds" axes while you still have a simple foreground of the park across the river.
This picture in general caught my eye, when on the full screen you can really take in the depth of the picture. you have a foreground, a background, and everything inbetween to really catch the eye.
