I like the first one ... I take it these were your first forays into nighttime photography and you had to make use of what little light there is for you?
In that case you did well: small aperture (giving you nice "stars" from the street lights), long enough exposure, clear, totally unblurred picture ... I like it! Nothing much going on in a residential area of a little town, is there? And yet ... you captured what is there.
The second is a nice concept, too. How did you stabilize your camera for that one?
