Thank you so much for all the great feedback everyone
I really appreciate it and I am very humbled by this great feature of my work.
To answer some questions:
I lit up the windmill and water tower using a torch during the single exposure for "Broken Dreams" by simply moving the beam all over the structure very quickly.
There is no real point in saying my camera settings for these images unless you have exactly the same camera and lens that I was using. What I can tell you is the key to these images is twofold. First and foremost is very dark skies, so no, I don't think you could do something like this in Sydney, David. The second is know the "600 Rule" Google it and it will tell you what it is but remember that it is worked out on "true" focal length. If you are running a full frame camera then true focal length is simply the focal length of the lens you are using. If however you are running a crop sensor (like me) then you need to apply a crop factor (Eg. Canon crop sensor is x1.6) to the lenses indicated focal length. Once you know your 600 rule then it is just a case of trying to gather as much star light as you possibly can within your time limit. That is what I have done here. They were all fixed tripod shots. No tracking involved. I hope this helps.
