Nice shot, everything seems well placed, the rail leads you through the main point of interest to those inside. A crowd of strangers living in there own worlds.
One of your best. At first I only saw 2 people, then I saw the woman looking out the window, forming a triangle with the other two. She holds the image together somehow.
What ciaeagle says; I think 'Isolation' would have been a great title as well. The more people live together in large communities and cities, the more they try to find their own individual space in it. Good story telling image.
I was about to post my comment, but then I read what the last to had said and I had written something identical.. This image certainly conveys some real emotion and a strong story. Great one
I like how the woman is looking out the window and her expression adds to the comment by pixelpig that they are waiting for the last bus home. What an interesting slice of life shot.
