Now I think this one is my absolute favourite of your entire London series. The perspective you have conveyed by use of viewpoint, coupled with the moody background has injected real drama into this image.
You mentioned in your intro that one day in London was not enough to do it justice, and I know what you mean. If you ever do plan to come back for another visit let me know and we could do the tour together, I think I could really learn a lot from your approach to photography ;-)
