The attached picture was taken at nite with a tripod with a 55-200 lens @ f4.2, 1/250, iso 1600, 62mm focal length.
The problem is your settings and Mitchell is correct about a telephoto lens compressing the background. When you take a night picture, you want to use a tripod, a lower ISO setting, a small aperture setting (f/5.6 to f/16 - diffraction could be a problem with a smaller setting) and a slow camera speed. Your image has a lot of noise because of the high ISO setting which was needed because of the shutter speed.
Here's a pic I took at night using a 35 f/1.4 lens on a 30D.
1/3s f/6.3 at 35.0mm iso400 (could have used a lower ISO setting)
This shot was taken from my driveway with a 17-55IS on a 30D.
1/4s f/2.8 at 55.0mm iso200 (I used f/2.8 since the only thing I wanted in sharp focus was the church steeple).
Here's one more just to show you a night shot with a wide angle lens (Canon 10-22).
1/30s f/4.0 at 10.0mm iso100 (this was shot without a tripod so I needed the f/4 setting)
