Im on chapter 40+ now and I feel like the art got worse over time. I mean, its more clean now, but less detailed and the background has become fairly standard. I know its not good to have too many lines distracting from the main focus (that is, the characters in the scene), but at this point, it feels like Im reading a novel, where the enviroment is described only at given times. This is the huge advantage of comics/manga: You can always have everything (background/characters/action) simultaneously, whereas in a novel, only one thing can be described at a time. Still, it is a lot more detailed than the average manga out there.
