I love the contrasting lines of this image.  The man made structure is in decline and made entirely of straight edges and 90 degree angles.  Nature is taking over and is made of random bends, twists, knots, arcs and different shapes.  To use a military metaphor, this is a hoard of Berserkers going to battle against the precisly formed marching lines of the Red Coat Brigades of the British. The Berserkers are winning and the lines of the Red Coats are falling out.
