On Location Waterfall With a Variable ND Filter 

Thanks for the video. It would probably be helpful to include information on how many stops of light the filter cuts, either in the description or as a card on top of the video. And since it's variable, it would be cool to see the same scene with all the options from the lowest to highest stop. I know this is a few years ago, and you may have implemented these suggestions, but just in case... in loud situations like this, you might find it beneficial to record your voiceover later in a quiet environment while watching the video. If you want, you could layer the audio of the waterfall as a quiet background sound. Also, instead of relying on your viewfinder, use the magic of video editing to show your result as either a picture-in-picture image on the video, or temporarily replace the video with a few seconds of the still. I know you added it to the end, but it's a bit more of a smooth transition to just show it rather than say look for it at the end.

Thank you for sharing us your knowledge, skills and the love of nature.

What is the filter setting in this? How many stops did it reduce?

Lovely location and a nice result too. Showing where your focus point was to get your depth of field would have been even better. Thanks from the UK.
