Working in the transport industry, I remember visiting Southwark Tube Station when it was just a (very expensive) hole in the ground when the Jubilee Line Extension was being built in the 90's.
The mid-level atrium now has some blue reflecive pannelling - had this shot in mind for some time as I use Southwark reasonably frequently on business trips.
Golly, you have a wonderful POV here and the curve and colors are great. I wish the photo had a different title or more of a throng of people. Still gorgeous, regardless.
Well worth the planning and the waiting.
