Turn off the flames, they look bad during the video. Same goes for trails (in most cases)
Be more careful with the keyframing, the camera pass through the ground, as mocucha pointed out.
If you're using a fast paced song, speed up the clip and sync.
A good way to learn how to sync is using slow songs, usually the beats/notes are far between, this means easier moments to 'catch' and make the tori move along.
The camera shake was annoying, Using different effects throughout the video makes it more interesting to watch.
