Ben, I enjoyed the site very much. I agree with Odie that the navigation may not be intuitive at first, but it adds drama and in my opinion it's a good trade off.
Bill obviously has a keen photographer's eye, and I do not. But I like he minimalist style, the abundance of white space and the simple sans-serif font choice. The contrasting black and white text on the "about" page is a nice little touch.
By the way, I'm using an iPad to View although there is noticeable banding of some shadows, it looks quite good otherwise. And it's hard for me to view your turnings without being humbled by my own lack of skill!
