Original idea, but it probably would not hurt to make the main page (with the tabs closed) fit in the browser windows without the need to scroll (at 1280x1020 you need to scroll right after you click on the elements of the accordion).
Also I could not see the websites in the portfolio. There is just that enlarged picture that is not even very clear. Links to the actual sites would be better, I think, people can navigate the sites and a much better impression.
