Many thanks, Glen.
The picture was taken at a nearby mall. From the 2nd floor I saw the woman at ground level and waited for a second one to come down the escalator. By chance she seems to be looking down as well. I emphasised the two colors in this version . A B&W version is in the street photography site.

Ah ha!
Lucky seven.
Four sides, three areas. Four feet stationary and three feet in motion (one is hidden.) And seven stairs.

Were you waiting for this sequence, or were you on the up escalator just at the right moment?

Good picture.

Sol, Jim, many thanks for the comments.

Excellent work, Carlos! Color, angle and composition, according to Jim, also captured my attention!

This shot jumped out at me. Love the angle & composition.
