I like it. A few points though:
Always use a CSS reset! You notice the white border that goes around your header? This is caused by browsers using their default settings. If you want that border there, that’s fine, but make sure you create it yourself after doing a CSS reset. For more info, just google "css reset", there will be a bajillion links.
The footer cuts of a little awkwardly on the sides. You’ve faded the top in, but the sides just stop abruptly, just doesn’t flow well for me.
All of the links in the footer give up 404’s.
On the About page there is a HUGE space between the content and the footer. That fixed height div has got to go!
