Nice job so far. One thing I noticed is that when you click on the bottom navigation to go through the portfolios, <Prev or Next> navigates opposite from what the user would expect, given the navigation list on the left side of the page. <Prev goes down the list and Next> goes up, I'd change that. One other thing, I'd lose the file size on the thumbnails if you can figure that out, just to clean the page up.
Nice job on the site and great photos too!
