In your rollover images all that changes between the states is the text size and position, you could recreating this using CSS and it's a:hover property with a background image. This would make the site more accessible and it would load much more quickly. CSS could also replace the Flash navigation, which is definitely a good thing. There's no real need for the Flash element at the top, it could be replaced by a static image and CSS rollover styles.
Right now it's very image heavy and took quite a while on my connection (cable) for all the images to load and for the rollovers to work.
The main content and look I like, it's just the top banner I'm not keen on. The images don't blend into each other and the colours don't fit in with the couor scheme maintained by the rest of the site.
