Great series here. First thing though is next time size them to about 800 pix wide, these are a bit too small. My favorite is #2. That is one cool night shot, I like the lighting and the reflection, and especially that little vapor cloud... really nice! But in #3 and 4, the horizon is off.
Looks like you should get around Kingston a bit more with that D300!
I really liked #2 it was a cool shot.
#3 and #4 were hard to take. I knew that #4 was off. But I still liked those two shots #3 and #4 because of the sun and the clouds.
