Well the quality you see in the faces is the same quality given to everything else in the manga. I would expect the animation to be on par with Ghibli to match the quality of the manga although from what I’ve seen in the first episode it looks like A1 studio tier stuff. AKA not great but not terrible either, just what you’d expect from a mediocre anime.
I mean jesus look at the detail.
I know it’s not a direct comparison but the manga rarely drops any quality where I feel the anime does not have the same attention to detail.
Once I get home from my last exam I’ll try to find a better example.
