Actually there is still some room for comment.
Eric, I understand you are trying to capture the "silk like" effect from the fall, and since on A40 you can adjust the shutter speed I would recomment you to use a shutter speed no faster than 1/4 sec in order to capture the "silk" effect.
Moreover, the composition of the picture is a little bit too "busy" try to concentrate on one section rather than capturing everything, you see the trees on the top are not necessary, if you can choose another angle to face the fall but not including those trees it'll make the picture more "peaceful".
Just my 2 cents, nice to see your 作品!
