I've been really retarded the last few days...yes. That's what I meant to say.
Now about the pics...definitely get a tripod for night photography or try to place your camera on a garbage can or anything that doesn't move. I try to use a timer so that the camera doesn't shake from me pressing the shutter.
Pics with the D80...they weren't all that interesting. I was distracted by the car in the background and in some of them you cut off a portion of the front end. The following is just my personal suggestion: Mustang is a sports car, shooting it from so low to the ground exaggerates the ground clearance making it look like a truck. Try shooting from a higher position so the car looks lower to the ground. Try to make sure there are no other cars that distract the viewer (unless you want multiple cars to be in a shot). Also I think it would've been a great shot if you went head on and shot the hood of the car with a wide angle...It's been done before, but I still like shots like that.
