The concept behind this piece is a deserted London street. There are clues about what may have happened, the bank has been damaged, there is rubbish strewn on the ground and a pushchair has been left in the street. This is ambigious as the viewer can only speculate about why the street is barren. The fog brings in a eerie effect,and could even be read as being part of the 'disaster' itself. The London skyline is portrayed in the background, but it is not lit, perhaps the disaster spreads to the whole city, or perhaps it is an isolated incident on this one road. The light on the right-hand side could still be an abandoned building with the light left on, or perhaps there is sign of life.
I included all these objects to create a very ambigious image.
