It lacks images...and the banner image took a long time to load. Nav links need to have a rollover. Overall, without imagery it's a very dull site albeit a clean one.
It is a very nice design, but I agree with the guy above. On my computer it does take some time to load and you could use some more images instead of just the one that is the same on every single page of the site. I do like the design though, its looking great!
