The middle one fascinates me most, I so like the effect on the lights the motion of the wheel has, this idea of ... what? A spiral? Something like that. (I detect dust spots in that photo, too). Though the zoomed-in first and the mere HINT at motion is really good, too. You went for what? F22? Very starry lights. I like that.
You can just get an Exif data viewer addon for Firefox, which shows embedded camera data when you right click on an image and go properties...It's alot easier than guessing
Btw, very nice photos, I love the effect the long exposure has given the sky in the first one.
