First thing I noticed was that the colors and fonts were light and did not contrast well. I needed to adjust my screen to be able to glance over the copy.
Like your header, logo and colors. Very soothing without being "girlie".
Since you site is flash based it took a little longer for page transitions and I get impatient easily. I also noticed that you have some good copy but because you are using flash and images there is no content to scan for
SEO reasons. Other than keywords in your metas you are loosing some oomph.
And finally, your menu structure. When I click on top level menus I get directed to a page unless there is a sub-menu in which case nothing. You should make that consistent meaning at least put a landing page with some info on the top level of all sections.
