You use vantage point and symbolism very well here, Krasimir -- the pattern of the floor suggests a universal context, embracing the three security officers who are oblivious to it. These officers seem relaxed and seem incongruously unaware that they, who are paid to do the observing, are being observed by your camera and by your viewers. Overhead views can produce symbols that are invisible from ground level. Your high vantage point creates the global context and abstracts the officers simultaneously. My student and friend Jen Zhou used a similar vantage point to express the tedium of waiting -- seehttp://www.pbase.com/image/32549923.
