This is an interesting play on shadows. I like one of the earlier comments about a B&W processing look - wonder how that would have come out. Anyway, noticed you online and it's been awhile for you. Looking to jump back in and enter some challenges again? Why not? Give it a shot. :-)
I find this shot to be flat, Im not getting a sence of the dept of the room that is causing the shadows to bend, and the rail at the bottom is becoming the focus that is where my eye is being pulled
The reflections off the glass are distracting, and take away from the effect you are after. Cropping out the stairs etc in the bottom also would have been better, as they add nothing to the overall effect
