She's definitely a good singer but her vocals aren't for this specific song. She tied in her aesthetic well with the music video and the editing was pretty good but the animation was subpar and really wasn't good. The only good thing about it was some of her vocals and the editing but I didn't like the checkered transparent background that's used when there isn't a background on a picture. Some of the scenes in the music video were unnecessary and the music video would be better off without them.
If the animation was better or if her vocals were a bit better I would give it a 6-7. But since her vocals seem really mumbly and quiet and honestly don't fit the song I have to give it a 5 but if I could I would give it a 5.4.
