Fantastic place for a photo shoot and you have done a good job. However I have a few suggestions but it is always personal choice and you may well not agree with me. Photography is always in the eye of the beholder.
I notice you have used a slow shutter speed to give a dreamy , fluffy look to the falling water. Photographers go for that slow shutter look almost every time they see fast moving water.
However, in this case I am confident the opposite would work well. Next time try a much faster shutter speed even though you will need to up the ISO considerably. This will give a different type of reflection in the water and the reflection of the falling water will probably respond well to a touch of dodging and localized sharpening. I would be tempted to crop a bit of the bottom and right side, then the vertical line of light the falling water and reflection creates would sit nicely on a third and enhance the composition.
A tip I was given many years ago, was, Fast shutter to freeze fast moving water will make it look full of action, slow moving water that looks dull can be saved with a very slow shutter speed.
