I noticed too, even a bit before chap 65 actually... I know that the artist was sick and that's the reason why they had a long hiatus + a pause every 3 chapters, but since she came back the drawing are a bit different (not in a good way). It's very subtitle but you can still see/feel it.
The webtoon is still very well drawn (especially compared to a lot of webtoons), but it's still lack compared to before.
I don't want to complain because I know the artist is sick, but it's one of my favorite novel so I can't help but pay extra attention to the webtoon ╥﹏╥

Am I the only one noticing the change in the drawing? More comic, less shadows,... The 65 first chapters were so well executed, the last 3 chapters are really different. There are some weird proportions sometimes, the chibi are out of the place (I don't recall seeing any in this manhua before the last chapters), the lights and shadows are lacking... I even checked if the artist and color artists change. Well, one of the color artist is gone in the last chapter, but I sense that maybe their publisher asked for less refined drawings? I don't know but I find this quite disturbing.
