Mt Coree Photos

Went out to Mt Coree (60-70k in to the Brindabella Mountains from Canberra) the other night for a drive with a mate in his new (14 yo) Hilux. Good drive up there, but the clouds descended over us once we were at the top. We ended up surrounded by heavy cloud and ghosty looking snow gums. I got a few interesting pics, please comment/critique them, as I would love some tips.
All lighting was provided by the reflected glow of car spotlights in the heavy fog, except for the last one (illuminated by fog lights).
30" f/20 ISO100
I have mixed feelings about this one: (same settings as above.)
My Favourite from the night:
140" f/8.0 ISO100
And a portrait of myself.
(Yes, I know it is a bit soft, I moved in the 0.5")
Please excuse the poor JPEG quality.
