I like how you lined up the crosses in the first image, It gives the image an abstract quality and still retains what the crosses and structure really represent. Love the third shot, but not sure about the second shot, however. The main cross seems to overly dominate. Of course some things can be considered cliche, but the way I see it, if you come to a scene and it strikes you in certain way, and you use the principles of good visual design and can depict a scene with a certain quality, who cares if it is cliche.
I have heard the Pentax medium format is quite large. People must see you coming from a long way. Wonder if that is any impediment to you freely photographing as you wander around.
