Hey, thanks for posting, Sarah, and commenting, buddingphotographer.
I would like to see a more dynamic angle. Get down lower so you can see more water in the background, preferably disappearing into out-of-focus texture in the background. I wasn’t there, but if you had squatted down, you possibly could have used the foreground rock as a secondary element in the composition. Your subjects are excellent, and your exposure is good too, but I would have put more thought into composition. Even adding something very much out-of-focus in the foreground would have added more depth too.
If you’re camera isn’t giving you the Depth of Field I’ve just described, move your camera over to Aperture priority and shoot at f/4.0 or f/5.6. With some zoom, you should be able to get some DOF even with a point and shoot.
Lighting is another thing to consider. The light is very harsh and colorless. I’m glad you took the shot when you did, but if you can, the next time you have the opportunity to stroll along the lake-side go in the late afternoon or early evening. You’re making the most of this opportunity, however, by having the subjects facing the light.
As buddingphotographer said, I’m glad you caught the action; it makes it more interesting than just two swans sitting on the shore, or swimming on the water like the multitude of swan pictures.
