It was hard to look past the technical problems in the video. Lots of nasty visual artifacts, pillarboxed AR, and subtitles for the lyrics. Don't put subtitles in your video unless it's absolutely necessary

(like for a sing-a-long)
As for the video content itself, the scene selection doesn't seem particularly inspired. I'm not familiar with Star Driver, but it seemed like you took scenes from mostly the openings and overlayed other scenes on top of that to try to lyric sync. My advice would be to take care of the technical problems first, and then try to get your scene selection to be more varied. Good luck!
