The whole thing is aesthetically pleasing, the animation is nothing special, but the stuff like character design and background art are forceful. From watching this I'd definetly start reading the manga if I wasn't doing so already. The music is your generic mellow J-Pop song, but I honestly wouldn't expect any other type of music from something like this.
The only real problem is that although it classifies as "anime", it doesn't really have much substance by itself, it only really works because it's just a promotional video.
Bottom line, as an anime, is meh, but as promotional video (which it's the only thing this should be considered as) it's pretty damn good. And in the vain of promotion, go read the manga! It's a cute and lovely yuri manga with some melodrama here and there, definetly worth your time.
