San Francisco skyline

Hi, I just got a new 30d a couple days ago, my first SLR! I took these pics from Treasure Island last night. C&C?

any comments? suggestions? Thanks!

Magnificent, I wish that I could see more of the bridge though..

Sorry to be negative, but I'm going to disagree with Rumrunner

Here are what I see wrong with the images:
1. Too much sky. Unless there's something of interest in the sky (like a great sunset for example), try and keep it to a minimum, especially for night photography.
2. Noise. This could be because of the resize for web, but it looks as if there's a decent amount of noise there? Either run it through an application like Noise Ninja (or even Adobe's noise algorithm), or choose a lower ISO. That said, sometimes noise adds to a picture, so use your discretion.
3. The city is very bright in the second shot, and also slightly soft. The trouble with taking shots at night is that your camera's meter has trouble metering for large black areas with small areas of intense light. Try spot-metering the city next time (maybe zoom in on it first), then recompose). Oh, and make sure you're using a tripod!
4. Composition. The city is almost "hidden" by the large sky and water, but this can be rectified by either cropping the sky out, or maybe making a pano to really emphasize what a great skyline it is.

Anyway, I don't mean to be doom & gloom. And I also want to state that some people might disagree with me on all of the above points, so it's just my opinion!
But if we all agreed on the same thing, we'd all take the same pictures and that would be boring

Keep at it man, and good luck!

Glad you liked it Rumrunner! Here's some more of the bridge for ya:

I like #5 the best, nice work

MUCH better pics well done. The crops have really done a lot to help the images.

Good work and keep going, you've done well.

Looking forward to seeing the pano

I certainly like the one's closer of the city. Great job on them! Practice makes perfect, so keep going out and shooting!

Great, Night photography is challenging isnt it? I love that bridge

Excellent bridge shot.

Cropping really improved the images. Amazing what just a small thing like cropping can do.

Awesome! I like #2 of the first two the best...the clouds and more intense light pollution make it feel very upbeat, like you can feel the excitement!

Thanks very much for the great comments, feedback & suggestions everybody!

The closer ones are awesome
