I think the artist here just changed? I might be wrong.
But yea, the thing is that a lot of manga/wha/hua artists are working themselves to death for a weekly (even monthly is a bit too fast) upload schedule and burn out very quickly bc of that. From there they either quit or start prioritzing efficiency over detail, because slowing down uploads is the last thing those production companies want.
Right! There are sooooo many artists going on hiatus recently, like an alarming amount of them and it's all due to health issues.
What comes to mind is the author of Roxana (aka the way to protect the female lead's older brother, aka a banger) who was hospitalized a year ago, because despite having a miscarriage the publishers were denying her sick leave and pressuring her to keep up with the schedule... instead of putting out one fucking delay notice. That's how bad it can get.
Lately most manhwa art are becaming good to weird. It's as if artist is losing their will to draw
