This shot is really amazing. The framing is really good and the subject perfectly chosen ; the metal part between the windows going through the circle of chairs makes me think of Stargate's gate ^^
It is unfortunate that this shot is so noisy, can't you correct it ? I know that Lightroom does correct color noise very well.
The reflect of the circle in the glass is also perfect ; but I think you could have chosen to place the separation line of the circles at the first third beginning at the downside, just a bit lower.
It appears that you're not the only one having chosen this building as a subject
Overall, I .
