I just looked through your website. I really like it. I think you have beautiful photos. I really do agree that you should break out a seperate section that specifically says destination. Because, although there is one picture where it clearly says Bahamas (and a few where you can obviously tell), someone coming from the outside who does NOT know you are a destination wedding photographer, might just think you took some really awesome lake shots in MN. Or they might think it was a fluke that you traveled.
I think in your ABOUT section you should say that you love to travel across the globe to cover weddings, or something like that. I also think you should maybe write out what the basic "coverage" includes.
Just my opinions, but I LOVE your work!
