Though I'd love to, I don't have time to use the D30 for the bulk of my seniors. How ever for special instances - like this one I used it. (special high end client, I used the D30 to shoot their daughters senior pictures at their summer place on the beach.
Here's a sample.

When ever I see a portrait done with a sunset in the background, I really dislike it because they had to use flash fill to get the subjects exposure to match the bright background. I like it so much more when I can get the sun lighting the face, and then duplicate the sunset in the background.
This was a quick combo of two images, I will probably edit it some since I don't really like the sunset this close to center.
