I think you have a good start for a site, but I agree with the comments made so far.
There is way too much whitespace for me, (1280 x 1024) and the design it self is too dull. You have a great start, but it needs to be more interesting visually
Looks ok at first glance but after I browsed it for awhile the whole site just didn't seem to make sense. The layout works fine but your choice of images don't really go with what your talking about.
May I add that the header image is (in my humble view, at least) too large when compared to the rest of the page elements. I also agree with DaveRH about whitespace.
