While I loved the interior art, it was baffling to me why the publisher placed each illustration where it was. Why was Shallan's drawing of the dog thing, for instance, placed hundreds of pages after the part where she draws it? I would much rather have had all of it a page or two away from the scene that references it.
Furthermore, why are all of Brandon's books so poorly proofread? With his first books, I assumed he was too new for TOR to want to invest much in the way of proofreading on him. Now that he's such a success, the continued poor quality just doesn't make sense. I am a copy editor, so I notice such things more than most people do, probably, but I also compare books with each other, and Brandon's seem to be in relatively bad shape typo-wise.
[Addition: My husband, also a copy editor, says the new Tad Williams book he's reading is poorly proofread too. He thinks that maybe publishers are just having to cut back on editing in this economy, or maybe in general in response to the changes in the industry, such as the move to e-books. It might be.]
