After some moments of looking, this image seems tilted a touch - which adds I think an unneccesarily distracting dynamic to what is otherwise a very fine shot for the challenge. I particularly like the fact that the strongest compositional elements pull the eye towards the stairs, and your hidden figure is in the other direction.
Either level it or give it a significant tilt, otherwise if looks like a mistake. There's definitely a great photo hiding in that scene, maybe with a titgher crop.
