These are some pretty cool pics. Better than I could take, at any rate. Keep it up, because you definitely have some talent. I especially like the shots with the shutter left open and the light streaks.
I can't wait to see what kinds of pics my wife gets next time we're at DLR. She also had a Nikon D40, but then she upgraded to a Nikon D90. (No wonder we can't afford annual passes!) She would love to be a pro photographer. Once we go to DLR, I'll post her pics for the MiceChatters to see.
