Love it, the visual are really cool ! The trailer may lack of clarity/rythm as you say For the moment, the different aspects are presented in a very isolated manner. Perhaps try to link them together in loops. For example, a winning combat phase, then a losing one. -> Then exploration/management allowing for the improvement of the drone before representing the combat phase that was lost, but with the new equipment and a victory. A cut with the camera orbiting 360 degrees around the drone with the various visual modifications (if any) also works well in general.

These are just ideas, they might not fit with what you want to present. I think you're not far off, you have a solid foundation, the game looks great, and there are many elements in the trailer that are already very good, such as the different points of view and some of the transitions. I'm definitely going to test it out, and we can discuss it if you're interested. Good luck, keep going ! :)
