This shot is very catching to the eye. First, the contrast between the couple kissing and the woman uncomfortably adjusting herself. The graffiti on the escalator of the young couple contrasts to the elegance and classic poise of the opposing woman on clean steps. It's at a good angle as well and cuts the two in half, separating the different people. The tones could be varied more, but you work with what you've got. Focus could be improved. It's a great capture of a simple moment. It's a neat illusion as well, seeing gradient steps and then people standing on them. Well done.
