The Sanatorium

I had the chance to meet a few folks from the Photography Forum. 
We went to explore a derelict sanatorium... It was very vandalised  (besides the natural dereliction) and it was quite difficult to find interesting subjects because no features remain. 

In this composition I tried to explore radials and diagonals. The first step of the stairs leads your eyes to the handrail and the handrail zigzags and drags your eyes to the exit door.. 
There is some tilt but I cannot correct the perspective more or I loose the first step of the stair.
