Jim, the site is nice and easy to navigate. I get what you do because im in photography also but I think you need more description on what you offer.
I'm not a fan of the all white background but that is only a personal taste.
As far as the images go, they look awesome!! The only thing I would change (if you can) is make them larger. When I click on the gallery, then click on an image, it pops up in a player of sorts and is somewhat small to my taste. Larger images would show more detail and in turn hopefully get a client more interested in hiring your services.
I hope some of this is helpful...
Best of luck to you Jim
