This is perhaps the most fascinating site you’ve filmed on this trip. Using your most excellent video as an example, here’s a couple ideas for combination moves:
For the opening shot, as the architecture has a clear centralized feature as a terminus, instead of passing over, if you slow forward progress and increase elevation as you tilt gimbal down, maintaining axis with the center, it provides a logical focal point for the viewer and an interesting visual transition. You don’t have to achieve a full straight down move, but it teases the POI’s and gimbal down spiral/rotation shots that follow. A similar move can be done in reverse for your closing segment.
For the gimbal down spiral shots, you might have set a spotlight in the center, then backwards away for part of a POI and then forward to the center for the boomerang effect.
I like the slide @1:52 along the straight wall. Good eye for the features. I’d make it a bit longer clip. I also like the elevation changes and forward/back on the POI’s/spotlights. Try a bit faster ascent/descent so it’s more noticeable.
As your video approaches the end is the most logical time to use the clips that are moving backwards and farther away from the site. They’d make for a better closing shot than the pass over, which should really be a wide and high departing shot with the subject in the center and wider landscape for context. @2:00 would be a better clip to close.
Try filming some more aggressive turns or other inputs towards the end of a segment. They make for really good visual transitions. Tilt down turnarounds come to mind. You only need a couple seconds to lead the transition.
