As I noted in my comment on this overall gallery, this image gives us a metaphorical glimpse of urban nerves at work. Overwhelmed by economic and social forces beyond their control, people who live in large cities are often concerned with personal survival, and this image shows us the survival urge at work in a fresh way. It is not only the most expressive image in this gallery (to date), but also one of the most memorable images you have made, Iris. It offers pure social commentary, presenting a basic human value (fear) in an abstract manner, and also in a way that any viewer can instantly feel and remember. The fact that the language on the wall is Asian adds still another layer of meaning to this image and this gallery.
