I like the long leading lines and the repeating ellipses along the diagonal.
Might be nicer cropped down a bit on the top and just a little on the left. This would simplify the image and make it stronger in my opinion. Still very nice.
Very nice, however, I think it would have been better cropped in from the left. As it is, I'm not fond of the large expanse of white. (I haven't decided if I like the lack of detail in the white or not as it makes the image very graphical as it is.)
Great angle. Very contemporary feeling. I would have cropped out the top background bit to where the walkway starts to curve for a total geometric/abstract feeling to this. Then I would have pumped the contrast up a notch. But that's me. Really like it though.
A tighter crop would improve this a great deal - remove the top of the fence and the fence on the left completely so we're just left with the main fence and shadows.
