The animation is different, but I think it's fine. The background art is still amazing, and the comfiness is as high as ever. I also enjoyed the OP and ED. I'm just very happy that a slice-of-life anime got so much content, as usually they don't survive after the second season.
Yeah, the new art looks good too, but the previous art style still looked a lot better imo. Maybe I'll get more used to it in a few more episodes, but right now it just feels strange and unusual. And yeah, the OP and ED are both good, but I'm still disappointed by the ED. In the previous seasons, the OP was fun and happy, and the ED was calm and relaxed, but in this season, both the OP and ED have the same fun and happy vibe
