For whatever reason, it does feel kind of "cozy". It seems that a deserted parking garage at night should be creepy. Very nice shots, I wish that we had some good parking garages here other than downtown and at the airport, but hey, that's what you get for living in the suburbs.
I'm surprised how captivated I became by something as simple as a deserted parking garage. The mood and colors are great, you did a very nice job with these.
