Lip Syncing Issue

Despite making another version of my song I still have an issue with my characters lip syncing. I have replaced the majority of the clips which have this problem with some footage of the character playing and singing inside. This was because inside it was far easier for the character to listen to the song and sing along with it. Because of the short amount of time I have to film more footage I have resorted to critically refine the footage I have to make it fit in the best I can.
