Create Depth

This picture creates depth because you can see how far the road goes, how many people are walking and running away from Manhattan. On the left side, it's very crowded because that's the left side of the road, where people would exit the city. The right side of the dividing wall is where cars drive, so it would be dangerous to walk on that side of the road, which is why more people are on the left. But some people are running on the right side, because desperate times call for desperate measures. You can see the depth in the left side on the picture, so many people trying to leave the city at once.
