I would do some cropping on pics 2 & 3 at the bottom of the picture; so as to get rid of distracting elements.
By the way those are great shots.
Yeah, I get what you mean. The 2nd shot, was straight from the image. No cropping. I could remove some, but then probably lose the left hand bridge support.
And the third? Well I just wanted to include the full rail, and then one without, but same angle (pic #4).
Thanks again. 
I need to get out shooting more city shots in Auckland. Haven't done any with 20D. Only been on holiday, beach shots, airliners.net shots, and that's about it.
