Hi Shaun,
It appears that you have already made your decision, but I am always wary about building an entire website in Flash. While it's true that most computers have the flash player installed, to those who don't, you completely deny them the ability to see any of your content.
One fix, is to detect if a user doesn't have flash, and if they don't, present them with a straight HTML site. This is a lot of work though, and probably unrealistic.
Onto other points...
I am viewing your website with a 17" laptop set at 1920x1200, while this is a high resolution, it certainly isn't unheard of, especially in the graphics and photo communities. Your flash 'stage' is not large enough for this resolution. The horizontal black bar at the top of the page doesn't go fully across the screen. For this reason, you may want to think about making a rectangular frame for the flash, and center it horizontally and vertically.
"Automotion" registered as "Animation" in my brain the first few times I saw it, and therefore was confused when the page had no animations.. I personally have never heard of the word Automotion.
Overall, I like the creative navigation scheme, it reminds me of one that I used a few years back at
www.infinityeventsinc.com . You may want to consider integrating your flash into an HTML page as I did in the website above, it could give your website the creative professional look you want.
