Lori,
That's a nice pose and location.
You might want to post the pic in the Critique area of the photo sharing to get a response. I messed with this just a little in Picassa at work. I fixed the horizon and brightened the highlights. Gotta watch the horizon when you're shooting near water. A good rule to try to follow is to try not to have the horizon slice the pic in half. Put it low to emphasize the sky and higher to show off the foreground. Don't be a slave to any rule, but it's worth keeping in mind.
Shooting at the beach, or where you have lots of white in the image means you need to do some special stuff to make the photo come out well. The camera wants everything to be neutral grey, which isn't white. The camera will choose an exposure that is underxposed. You need to over rule the camera and over expose the image to get the whites to be white, not grey. This happens at the beach, or when you are shooting a snowy scene.
Bryan Petersons Book, Understanding Exposure will help you a lot.
Keep shooting!
