Something is missing

It seems like a ok image when I first saw it, but it is not. The more I see it, the more I feel something is missing. Now i think the image has the good atmosphere, but the story isn't there. If someone or something at the bright side become the subject, it will create the linkage between it and the silhouette people, then it will become a lot stronger. Unfortunately, it isn't, so that I removed it from my Flickr.

You may ask, why I need to removed it from my Flickr, the reason is I want to maintain the stream with my strongest work from now.
