Thank you all for the nice comments. I'm glad a lot of you seem to like the 3rd one. To me it seems really 'bleh'. I was far more interested in the pipe bridge thing than the factory. And like I said, I just took the shot because I was there. Figured I'd just see how it came out. Some other time I'm planning on going back to a different part of the place and doing more night/ long exposure shots. Hopefully minus the fog. Try and get a different perspective on the place I guess.
Anyway, in case you care... 1st/ 2nd shot at: f/8 30'' 100ISO, 3rd shot f/8 15'' 100ISO.
For you Chan...

For anyone who wanted to see 3rd bigger...
