Great shots, but I have to agree that the haloing around the tall building in #1 and #3 are a bit distracting. When making HDR images, I've found that I almost always have to process the shot several different ways, then cut and paste the good bits into one final image. For example, this shot was processed three times: once for the water, once for the sky, and once for the pier, and then combined into one image.
These look fake, but not in any sort of bad way. It's something that you don't see every day and something that I personally wouldn't expect to see in this way. I love the pictures. They make me want to stare at them and find something new with my imagination. Well done!
