Good job ! Did you film in full 1080 or step it down a bit. 1080 produces huge files and takes a good computer to process quickly for editing
I may suggest moving your camera to different mounts and edit it all together. Getting the right tilt angle if you wear it on your head is crucial or you will end up with too much video of the ground or sky. Next time, I will have a friend carry the camera as well to get footage third person style. Here is my first vid with the same camera.
