Well i cant give any advice but i must say this looks Awesome!! i love how the red and white lights are all blurred! Its realy great! Well done!

You did just fine if this was your first attempt. If you have manual controls on your camera, you might find that a smaller lens opening will give you a much greater depyh of field
( area of sharpness from near to far). Your buildings on the right are much sharper than those on the left. I would suggest f/8 or f/11, and the camera should still take care of the exposure time automatically.
You'll always get the light trails, which is what makes it interesting, but the stationary building lights, etc, should be sharp. I assume you were using a tripod, or some support. Tripod is best for these shots, as the exposure can be fairly long, at smaller apertures.
Good job. Keep experimenting. You'll be amazed at some of the
images you come up with.
