Good shots, spotila. The first two have pretty good compositions.
One suggestion I'd make is with your second shot. If you have a manual setting, use that so you can override your camera's autoexposure setting. It looks as though it took a matrix metering and that ended up leaving your buildings a bit underexposed. Either that or use a bit of fill flash if you don't want the sky washed out.
I have a question about your third photo. Why are all the cars on the wrong side of the street?
Not bad images, though.
