Watch for those "crocs" jumping out of the water and gobbling down a drone! LOL
Agree on time of video - start to lose interest after 2-3 minutes and definitely get closer to the action or use the zoom video modes. Focal point is the boat / skier - but having the river banks / homes helps with perspective. Going high and having a lot of "extraneous" scenery to the sides takes away from the true focal point(s).
I do understand wanting to stay up high and not dropping a drone into the water - but seems you have quite a bit of height to play with.
