Great locale to fly. It sorta dictates flying lower, closer to landforms and features. The most interesting features appear at 0:20 and 0:45-0:59, 1:55-2:00. I'd focus more on those features using spotlight/POI w/ pull in and away(boomerang) and elevation change, gimbal tilt reveals forward and back, etc. Initiate gimbal tilt down by slowing travel, increasing elevation to maintain axis with the point of rotation. This is very dramatic when passing over a feature. A tilt up reveal works well with gimbal starting about 45% , decreasing elevation to maintain about 1/3 horizon as it reveals (sort of a swoop down). Another dramatic shot that always looks good and cuts in well is the gimbal straight down with very slow travel (otherwise it's all a blur).
Long sequences of straight flight or POI can be speed ramped to get to the focal point quicker. Practice very subtle arc turns to follow landforms. Make sure you've greatly reduced yaw speed and gimbal speed in your settings otherwise any of these moves will appear too abrupt. Spotlight gives you the most freedom in combination moves as you don't have to yaw, which is the nemesis of smooth flying.
The high and wide shots are fine infrequently, but the additional footage from the moves I suggested will provide a more comprehensive shot list to edit from.
