Thank you for sharing. I think you should work on slower movements, especially when yawing. Also, try editing the videos, so they are shorter and so that you can remove the unwanted movements. A good free option is VSDC. It has many features.
Thank you guus for the suggestions. These are the things I'm aware of, but just wanted to share the original footage.
