First of all, there is WAY too much empty space up top. I'm using 1024x768 resolution (With tabs in Firefox) and I can't see everything. It's cute but very user unfriendly, navigation-wise. Navigation and content areas both need to come up by about 500 pixels. People will get really tired REALLY fast if they keep having to scroll down. And the majority of internet users use either 800x600 or 1024x768, so you need to make it something that they can use easily.
