We can see author improved from their last work.
It's directly more compelling in the first pages, whether it'd be through the content of the story or the pacing of the panels.
The art is more unified too, with less empty white space and more pronounced nuances of darkness and light.
Don't get me wrong, it was clearly wanted in some panels in their previous work, but I think it was harder to link the two slightly different atmospheres so flawlessly, whereas there is no such feeling in this one, I can clearly feel only one art style, period.
The difference in art styles isn't noticable anymore after
the third chapter anyway.
