Great set from which I prefer #2. I think a cloning out (if possible) of the people in #1 would enhance the image. #4 is also excellent. I am little unsure of the perspective in #3; did you consider correcting it? IR is great, at the same time it eliminates concepts like colour. When do you decide that IR is the best answer for your intent when taking the images?
Irrespective of other issues people may have, I like these a lot. They are very dramatic, and capture a mood, as well as an image.
Well done.
