Did you use a night vision lens or something on the photos? It all was very monotone and at first I wondered if you used only green light, but they didn't have much lighting depth so that leads me to think the night vision thing.
There is a way to take good night pics without washing out your colors. You need a tripod or a handy stepladder to put your camera on, and then use the night/long exposure (no flash). The tripod/ladder supports your camera and eliminates the blurriness that typically happens when you try to take long exposures by hand.
