Still waiting for it to load...43%
What on earth have you got in there?!!
I have seen all kinds of flash websites with heaps and heaps of content/images etc, all loading faster than yours... Unless you do so already, seriously consider loading content when the user interacts, and not all at once!
Also, put an interesting animation on the loading screen, to keep people there. Or perhaps some introductory text (loads quickly) - you don't want to have a loader for the loader!
now 75%...
Edit:
Very nice site, certainly reduce the image quality (check export settings).
You could make the menu (on the left) load initially, then when a user clicks on the links, load the content for each link. That would save a lot on bandwidth.
I would suggest that you have too much animation going on, distracting from the main content. The changing title and white line animation is just a bit much. Looks nice at first, but distracts thereafter.
