St Pancras railway station, London.

I took this one in March last year. I love the architecture in this building.

I took this on the way out of the main hall of the Natural History Museum in March last year. The whole of the main hall is spectacular and would be fantastic fun to photograph if it wasn't always packed full of people!

Canary Wharf tube station (2)

I took this during my London trip in March this year. These escalators take you up to ground level, heading towards Heron Quays.

Canary Wharf tube station, London.

This one's from my recent trip to London. I love the shapes and light in London's stations - in this photo the light is pouring down into the station from the exit, silhouetting the commuters. Usually I don't like to have people in my photos, but here it works to give scale and motion to the scene.
