Cool places, since this is a critique board ill say that on number four, you may have raised your aperture a bit. As is the foreground trees on the top left are out of focus while the bottom foreground and rest are all in fine focus. This could have also been caused by wind swaying the branches. Also in the first photo it may have been better to have the first staircase a bit to the left more. That way it would have formed more of a path for the eye to follow into the ruins and out again at the end staircase. You may want to try and not center your subject quite as much as well. If you don't know of it try looking up the rule of thirds. sorry if these are no help, I don't usually critique, Im just trying to be helpful.

I don't mind the composition of 1. The only major suggestion I have is that 3 needs a little straightening so the vertical lines are parallel, and that would be a striking picture.

Cut off a lot, or don't cut off at all. The roof in the last one i mean, it's cropped awkwardly.

I love how vastly different but interesting each shot was. very cool. I have no criticisms here
