You will be led to the knowledge of the internal things which are invisible to you, by the external things which you see before you. . . . Even so then, we can represent to ourselves in thought the Author of all that is, by contemplating and admiring the (visible) things which He has made, and ever brings into being.

Oh! I do like this shot. The curving sea oats all strengthen each others participation in the image. They break the strong horizontal of the shoreline and the horizon and produce a strong contrast. It's hard to go wrong with sea oats if you ask me. The posts on the beach are a bit unfortunate though. They are the only man-made elements in an otherwise natural image. I think if it were my photo I'd try to use a paint program to clone them out. Also You might try this in black and white. It won't get as high a c-index in black and white, but I do believe you will like it better.
All in all this is a beautiful image, and it has a lot of potential. Good work.
