There are lots of connections here. The bridges across the water, linking the dense growth on the banks and they are close enough and they seem to converge, giving the appearance that they too are linked. The two people are linked by their interest in fishing and so too their links to the water. The woman is linked by the perfect colour match of her boat to the man‘s fishing float, and from there by a leading fishing line to the man. Both are connected by the seeming contentment and tranquility they are experiencing. Although their surroundings look peaceful enough, the mix of brutal, functional engineering and the natural filigree chaos of nature creates an atmosphere of tension, which is offset by those two peaceful islands.
