This is a stairway on the side of a multi-story railway car park. The tree is actually in a park across the road (some 100 yards away), but from this view seems to be mysteriously growing inside as if the stairs lead up to its upper branches.
This is such a great shot M. It looks so elegant and professional. I love that the colors all work together making a cool shadow effect with the brightness of the stairwell. Very good job. This is one of your best so far M. I love it.
