Ah, so I'm not the only one. I can see/hear that something is needed to cover the monotonous white sound of water going over the weir, but I'm not sure the sound balance is quite right. The water, the music and your VO seem to me to be competing at almost the same volume. Perhaps a change in music, as well as the nice change in volume, would have helped when you went to the quieter area above the weir.

Visually, however, it was great, lovely, soothing - long clips to suit the mood
