looks very cool. love the colors and the light. jello is distracting, i would edit those parts out. also some of the shots are overexposed. the d90 tends to do that in low light, so make sure you lock exposure at something brighter or you will just get excesswive noise and pictures that look almost like daytime. most of the shots are perfectly exposed though, i'm sure you can tell the difference.
It's hard to see noise on the lcd but you can tell that there will be if the image looks bright even at night. The camera doesn't "know" it's night so it pushes the iso way up to make it look like day.
