A clear day (and night) for Cyberia

It's a good day for photography here in Cyberia today,so grabbed my camera and took 3 simple shots.Enjoy=)

Photographers' section:

The day shot was taken with auto white balance and a general purpose zoom lens with maximum aperture of f/4.0-5.6.

The night shots were taken using auto white balance,same lens as above,but with a tripod(their shutter speed were 4 seconds)

Personally,I think these shots were not the best yet,so feel free to give me some comments and suggestions.Everyone needs to improve,right? =)
