Some real nice shots there. NYC is the best place to shot so many things to capture and an amazing skyline. I went at christmas 2 years ago and the flag on wall street on your last picture was made of lights instead of the flag, Really good. Cant find the pics though. Dam it!!!!
Yeah, I used the CS2 merge to HDR function, local adaptation, and tweaked the heck out of the curves. For the last two, I ended up pasting in the sky over top of the HDR shot from one of the photos used to make up the HDR -- the clouds moved too much during the shoot and HDR rendered them really weird.
