I don't care for the navigation system since it just leaves each photo on the screen if you click on another. Most systems will close one photo if another is clicked on.
Since I don't know the purpose of your site, I can't say much else. If it is designed to further your photographic business, then it will not work very well since it is basically search engine invisible. There is no Search Engine Optimization (
SEO) at all, so the site will not score well in the search engines. This is naturally a critical factor for a website that you want people to find (other than by giving people the link on a business card, or an ad).
