Watchful

I saw this lady and her reflection sitting behind the wigs in the window of the school of music in the Barbican. The window looks out onto an enclosed walkway so the light isn't very good.
As I snapped a second picture she turned and looked at me. It's not very sharp but I like the look on her face of "What do you think you're doing out there?"
Of course the wig heads had already seen me.
