The animation style isn't anything extravagant, but it's perfectly alright. It's very, very '2003' and if you like that sort of visual style then you'll enjoy it, but if you don't then it'll probably just be par for the course. While the anime is definitely alot more grounded it might've been nice to see some more interesting movements or exaggeration in some of the comedy relief parts, though obviously that's a matter of directing taste.
The music was also pretty decent, though I think the ED on the second episode was the highlight. The voice actors are all pretty good, though Hiyori was by far the best, though I can't say if that's more her character having a bit more varied direction.
The only real complaint I have is that with such a short runtime, it does have a bit of a tendency to hyperfocus on seemingly random plotlines and ideas - some characters get introduced if only to deliver advice and are never heard from again and the anime 'doubles up' on some of the imagery and themes in a way that just makes them feel a little bit less focused and clear than they could have been. Honestly for what it is, I think it's really underrated and deserves more recognition.
