[PNF]

I love the composition of the photos!

You probably did this on purpose, in the first photo, the lineups and walking of the people seem to form a "X", while the circular staircase provides an interesting contradiction. (you know, O vs. X)

I dont know, just me thinking too much probably,

but good shots.

The only thing I'd add is that, maybe increase your aperture to the MAXIMUM to allow maximum depth of field, which would blur the circular staircases even further and let the focus on the people, or the other way around.. I dont know, probably too difficult/not doable. Maybe also decrease the ISO a bit to decrease the noise a little bit.

Just my 2cents.

Great shots already though and composition > everything else.
