I love the execution and outcome and can feel your ire at not having willing subjects to photograph.
I like the 3rd one. Perhaps a tad more space on the left, and clone out the black line at the bottom of frame.
All kinds of terrible puns come to mind when I look at these.
Regardless. they are well thought out and executed. You have used the hard lighting to your advantage. I doubt people would have looked nearly that good in those lighting conditions. I agree with Greg and John; #3 could use a bit more space, likely on the left, right and bottom. Both the subject and the shadow are running to close to the edge of the frame.
