Except for the fact that it doesn't validate, and it's so Flash-heavy (which was to be expected, being that it's one of your sites

), I think the site looks fantastic. Very nice work on that. I can't really make any suggestions, except for you to do what you can to validate it properly.
May I suggest downloading the
HTML Validator extension for Firefox? It's been a lifesaver for me recently, especially since it will automatically tell you if any page is valid, even if it's a password-protected page (which you can't validate using W3C's online validator), and since it automatically points out the errors when you view the source of the page.
