This is a beautiful piece in its simplicity and surreal feel. The white line and obvious solidity of the ground prove it's a road, but since it fades to black at the end and has pools of water on either side, it can easily be interpreted as water and the white line becomes a sort of tight rope, suspended over the abyss. And the pathways on the sides are what really make the surrealism come to life because they look more like walkways at a dock, adding to the feel that the couple is standing over a river.
This is just really a fantastic piece. I could stare at it forever.
