This would have been better if you had a guy come in and plaster over that window so the backgrouund would be more uniform. But, barring that, nice shot. I don't usually notice the stairs, so full marks on the POV, also, I like the deep depth of field.
I can't help wondering what this looks like shot from the center pole looking down. But then, that would be the expected POV, wouldn't it. This one makes me dizzy enough. Nice shot.
Good concept, but 3/4 of the shot is distracting. I'd suggest focusing on what is in the bottom left quarter of your shot, making your shot more concentrated.
