I can only assume you're referring to the site in your profile:

If so, I think it's a good start. Nice XHTML, although, you seem to have the concepts down, you're still using Transistional. With that code you should fix the little things and go Strict.
Other comments:
You may want to change the body text to a serif font (Verdana or Arial are basic, but good).
Also, you may want to bump up the contrast on the navigation, perhaps a darker bg color?
Otherwise, looks pretty good.
