This is a very old photo that for some reason had been labeled as private in my photostream, all I did was change its status, I have not re-released it, my apologies if it has appeared as a "new" post, I would not have done it if I'd known as this is some really early work that does not represent my current output. Sorry for the inconvenience. The tower of Nash Point Lighthouse, South Wales, in background.
