The idea of using a cell phone to shoot the video and having it vertical is pretty cool, really "now". But I didn't really like how it only was her holding the phone, the whole video.
Sure that's one could expect but Namie also used the cell phone/tablet thing and made something interesting with it; Epil High also had a vertical video that played on that phone/tablet thing and they used it in a different but still interesting way.
Anyway, she looked great! I'd use that video as a fashion reference

I really like the song as well
