Both simple and gorgeous. Difficult to do as most of us know. Thanks for sharing.
In the first video, two minutes in, the lower half of the image seems to go flat, as if there is too much filtering, or the color range was compressed. I suspect you ran into issues with grading that. But, still beautiful camera work and coordination with the music.
For some reason, the simple shot of the boat coming in, with its wake trailing behind it, combined with the cello music, really grabbed me. I always treat the highlighted area of the ocean as a defect, to be avoided, and you made beautiful use of it.
