Thanks Nik for sharing your travels!
This picture is intriguing and forces me to rethink my general (and probably unfounded) antipathy with automatic "milkyness" of fast water in landscapes. I have learned to appreciate this effect somewhat. The scanning backs give a 3rd look. However, I like to see spray and ripples and droplets in the air arounf a waterfall. That's jusy my preference.
Here, Nik, I would be totally stymied! Unless one has a powerful flash, very slow shutter speeds are needed gives the milky dreamy look that people celebrate. So the first picture forces me to look at things in a new light and I must say I do like it. I would love to see this picture with the brightness boosted as there's a lot of detail in the foreground river bed that could help anchor the image.
What is pushing into the image from the left? Is it a shadow or an OOF bush or branch?
Did you add that Northern star or moon?
I think that this picture could be worth a lot of work to bring out its potential in a print! If you go that far, I'd love to see the final result.

The second picture I save my comments until after others have posted!
