The art style in the comic is so nice and simple.
Each character is just made up pf simple shapes that doesn't really break the silhouette much ,but the artist does a really nice job of finding ways around that and still making the images interesting.
I like the limited amount of colors that is being used. Lots of dull purples with bright blues. A big use of just geometric shapes in the scenes that keep it really simple.
There are also different fonts for each person, which seems to further push the illusion of each character having their own voice.
