Tbh for me it's really not that worse, if you're talking about the extra then yes they definitely look different. In the extra they look more like back in chapter 2. Considering about art progressed you can check out the author's new webtoon called "Our Sunny Days" the art is definitely way better than this one
Usually webtoon art gets better as the comic moves along but in this case it actually got worse as it progressed. I'm guessing the author/artist became exhausted and overextended like a lot of them do. Still a great series but something I noticed.
