Wow, thanks for the feedback.
Let me know explain the first two shots are using CS2 to do a HDR merge of a number of shots.. both at the end of the process I chose to different finishing methods. One was to adjust the exposure and the other was to reduce the highlights.
The shot that seems to be a winner is #3, which is just a single exposure, but I've worked the curves (I had a phobia almost about playing with curves as I don't understand them well) I thought I'd gone way to hard on this image, and it looked to extreme for me (on my screens) yet it seems to be the crowd favourite. The AMP tower has just been resized, and sharpen with a little tint tweak to make the sky a "nicer" shade.
Thanks again for the feedback, looks like I need to learn more about curves..
