Pardon me for saying this, but its GHETTOTASTIC

!
Just messing with you. Your design is very clean, and some people really like that (especially dial up users). But the main thing you need is content! I have found that with my team website, as well as many others. They just simply don't have enough content. Instead of making it pretty, focus on the content (which is all you have time for anyway). The judging has already started, and your website is rather bare. Good luck though, and I think it will be turnout great in the end.
P.S. Anyone know if being CSS and HTML valid influences the judges at all?

I went for browser compatibility!
EDIT: I just realized where I have seen that styling before -
Think Geek has nearly the same colors and bars. In fact, they seem to be the same size and everything! Just without the side navigation columns.
