The work you've got on the site is great. A few of the pages gave me side scroll bars (my res 1280x1024), and one thing i've learned is that people hate scrolling sideways.
Personally, i'd change the font for the text on your page and i'd lose flash for the navigation. Flash sites seem to annoy me unless they are outstandingly sexy to look at, even then the novelty wears off after a short period of time.
dannyngan, you may not have flash 6 player installed, that's what the navigation menu is made in.
