Quite nice! If possible, put the set of four links along the bottom of the page on all of the pages except the home page, so that you don't have to hit the back button as much within the site. Other than that, list exactly what boards you are competent in. I saw the "training" section, but I would enumerate the boards and models that you have worked on.
Also, how'd you get the domain name/what'd you use to build the site?
It looks great, no complains there. I'll second the adding more links. The other thing you might want to consider... it takes a LONG while for each page to load for me because I am on a satellite connection and those images are rather Large.
