I don't have any experience photographing architectural photography, but I'm a big appreciator of it so I think I can still safely critique it. Plus I don't have anything bad to say about it, since I can't find anything that I don't like about this photograph.
The thumbnail was already intriguing to me. It felt like I was looking into a tunnel at first, but when you watch it in full view, it soon shows that you're looking down.
The contrast is simply great, the black and white make the lines and textures really stand out and that light is just excellent.
I love how it looks like some kind of maze.
I must also compliment you for looking down there in the first place, since I have a terrible fear or heights and would've come close to the edge in the first place, haha.
I love it but, if the elevator isnt working and there perhaps was a fire if you try to go down the stairs you would have to run in half a circle a couple of times to get down to the 1st floor. (But ofc there is a fire escape somewhere so it isnt really that big of a problem)
