Pretty sophisticated for your first go. You'll probably want to turn the scrolling on in the left frame. I'm viewing it at a screen resolution of 1024 X 768 in Internet Explorer, and I cannot see the bottom of your navigation bar or the far right portion of your banner.

It's always a good idea to look at your web site at a resolution that matches what most of your potential readers will be using. At the moment, I'd say 1024 X 768 is the highest you should design toward. I still shoot at 800 X 600 most of the time.
