It's incredibly obvious. I'm guessing the artist was having trouble meeting deadlines and switched to a simpler art style to avoid overworking themselves to death. The anime/manga scene doesn't have a good rep when it comes to treating their artists well. It's a shame though, I'm sure the artist preferred the first style too.
Hm it wasn’t so noticeable to me but could be because i read the other season months, but as you said artists are overworked and i don’t know if the negative comments about the art will discourage them also this season just started and the creator took a break so maybe it will adjust will time
It was incredibly obvious, especially if you come from binge reading season 1.
Why is it such a big deal if the art style changed a little it’s not even that obvious
