Hi Jean,
This is a great sunset captured at a beautiful location.
There are a couple of interesting design ideas working for you, and the one that I like the most are the repeating headlands in the left of the frame.
Now, about the only wasted opportunity here is the tinny with the fisherman. it would have been so much nicer to have seen them silhouetted against the reflections of the sky ratther than being lost in the reflections of the trees. All that you would have needed to do to improve the photograph would have been to have walked just a few metres more towards the left of the picture.
Otherwise this is a nice photograph. Well done.
