Pity the ducks are gone. You gave us such a fun puzzle with the last one. As for this photo, I see the plants as the main focus point in this composition. You might want to adjust contrast or selectively change the lighting to make them more prominent. I'm really happy to see you are having such a good time with that camera. It's great to vicariously share in your enthusiasm. We are also being treated to views of Cape Cod that most people never see. At the end of the summer you might be interested in putting them all together in an album to commemorate your summer's shooting.

This has a really nice minimalist feel to it. I really like that there are different areas of grass and a nice horizon line that is high in the frame. You did a really nice job of getting our attention with the grass in the foregrouund and then we can move on toward the horizon where there is more grass. In between There is an open expanse of water which I like very much. To my eye the whites are a bit overwhelming, and the separation between the grass and the water could be more dramatic. As an exercise in what is possible, I worked the photo in a completely different way which, I think, keeps the minimalist feel; but enhances the contrast between the water and the grasses. I used the invert tool in PS. With your permission, I'll post it in this thread.
