I liked all but the first one. The building stole some of the focus away from the fireworks. With that said, the capture was right on and you did a great job on all of them. I wish I could shoot fireworks that well.
looks like for most of my pics iso was around 400 exp stop was down 2 steps and i was running around f22 with about a 6 sec exposure. the first one with the resort in the picture was an iso 100 with no step down on the exposure since i wanted it brighter.
