First impression: good. I like the graphic design and the colors.
If I were you, I'd try not to use tables in your source code. With so much for the browser to download (namely a lot of images), your site will load much faster if you just stick to CSS.
Your code is far from valid
. While it's not killing you in Firefox, I can't say you won't have issues in other browsers.
BTW, I'm looking in Firefox 3.
