If I had one tiny criticism about the site it's that the menu bar, once it detaches and scrolls with the user, is a bit hard to make out because of its transparent background.
Thanks for the feedback, i think this may be a browser issue as its intended to not have a transparent background. Would you mind sharing what browser you were viewing the site in?
You're right. At first glance it just seemed transparent to me because it has that gradient at the bottom. A better complaint would be that since the background color of the menu matches the background of the page it's hard to make out the options.
