Without reading previous replies (I hope not to repeat anyone), and if you allow me, some tips to improve your future videos:
Try to ensure that all scenes have continuous movement (camera & drone) and that there are no erratic movements of the drone. Cut the parts where this is not the case and when recording, keep in mind that you need N seconds of continuous movement for each scene. Video editors with stabilisation can also help you.
Try to have a variety of spots, shoot from different angles, heights, combine camera and drone movements, ...etc. What I mean is that videos tend to be more interesting if they have a variety of content. If you have very little varied content, make a very short video, which will always be better than repeating scenes or making them too long.
Hope this help you
