Natural Light Architecture

Subwaystation in New York.
As it wasn't allowed to use a tripod inside I had to shot this handheld. There is a little balcony on each side where i tried to lay down my camera on the railing.
I tested the exposuretime to where the image is still sharp but the people are blured. I found the combination of the moving people and the stunning architecture very interesting.
Sony a6000 with Samyang 12mm (aperture is not know due the samyang is manual)
exposuretime 0,4 sec
