This was a narrow space, so we wanted to increase that sense of speed in the POV, the stair and the ceiling converge very rapidly into the vacum point and once the eye is set on that point you can see the columns on the left side of the picture.
To take time to make a good composition is always good for the image, and good architecture helps a lot.
It was necesary not to show both side walls, since it was very narrow there and we wanted it to show more space in the image. Not showing one wall generates the illusion of and endless space to the side of the image
The stairs and the ceiling are both in opposite angles and towards the windows, that helps to the unidirectional view.
