I have recently started to follow the assignments on Dedpxl which goes back to basics and is primarily designed to improve your visual muscles. I missed out on the first one which was lines but the second one relates to repetitive shapes. I felt that the foot tunnel in Greenwich was perfect for this assignment with the light forming these dramatic continuous circular shapes. The difficulty here was getting a shot without people in it and required patience.  I might go back one day at a quieter time to get a greater depth into the shot, but for now this is my submission.
