Overall the design looks nice and clean, Jay.
One thing I might suggest ... That row of links at the top of the white box when you click the 'Savitar' tab ... About, FAQ, Screenshots, Download, etc. ... They disappear when you click on any of them, and to go to another page you have to either backtrack or click on the sun logo at bottom or on the main 'Savitar' tab again. Extra clicks. Plus people can get lost if they follow a link into one of the inner pages, like the 'Download' page. (I did, and it took me a few clicks to find where the Forums had gone.)
You might consider either copying those links onto each of the pages, either as they are or in some smaller but still navigable form.
Just my $.02. Otherwise looks good.
