I really enjoyed your videos so far! You've done a great job at capturing some spectacular scenery. Also, you have an advantage in that there is more than just a sailing couple- it's often more interesting to see different reactions and story lines among the crew. (instead of one filming while only one is sailing/exploring)
Small (pro) tip- some of your awesome scenes are in need of just a little color correction. DaVinci Resolve is an amazing (although a bit tricky at first) color corrector application that just happens to be free. You could waste a ton of time on it, but normally just a (small) bit of extra saturation is needed for certain cameras, especially on cloudy days. Finally, a polarizing filter is a really cheap
trick (either drone or hand-held) to wow viewers in those beautiful sunny waters.
Well done, though. We're watching now...
