I read many comments about how the novel was more detailed and the art delivery was not really delivering. In my opinion, this is totally normal as you can never get draw everything that was written (I am not defending the art here, just stating a fact). Also this is not the only art that shows a huge gap between it and what's going on in the novel, I have seen the same thing on other works here. I started reding this novel and man the difference between here and there is enormous. It could be a budget thing, or it could be anything else.
But the general idea is that the more visual you get with a story, the less details you deliver. A very vivid example would be movies based on books, the movie delivery is always poor and shows about 10-20% to the book readers. It's very rare to most never happened where readers were actually satisfied with a book delivery in a movie. The depth is only in books and novels.
And the art here is way too much superficial, it's like every chapter in here is illustrating the general idea of every chapter in the novel.
