Very nice colors and a good subject for this challenge. There appear o be some large spots on the right side of the photo, as if there are water spots on the lens or some muted lens flare. But regardless, the shot came out really well - good job.
I very nearly used the Sky Tower as it was the first idea that came into my mind. It is nicely lit and the green & red compliment each other. There appears to be dust or moisture spots in the sky which is a shame because I like the way you have exposed this.
I like the intense colors of the tower, but I can see some large connecting lighter circles in the sky, from post editing?. Make sure your monitor is calibrated correctly, unless it was intentional.
The buildings and lights in the foreground add nothing but distraction. you could have cloned them out or made them darker -or better yet, tried a different angle on the tower.
