Hi Gary, first off, congrats on the new book project. You've done a lot of good work so far. Some quick suggestions to help others that might want to chime in--add page numbers to your spreads, and add a thin faint gutter line.
For the line drawings, I love how you start off with a perspective from high above. There's a feeling of momentum, that we're about to go on a wild rollercoaster ride, with lots of slow-fast-scary-hohum moments. The following spreads show variety in perspectives, but then in the middle spreads, there seems to be less variety. Of course, it doesn't help that you can't do spots, vignettes and one-pagers. Maybe with the spreads that are next to each other and have a similar or same perspective, you can try placing the camera behind a character showing their POV? Or if this a slow sequence, just shift the camera slightly to add some variety? Then going back to my note about a rollercoaster ride, I was hoping that there would be some stage where fast action or excitement was evident. Without the text, and just looking at the images, everything seems to be proceeding at a generally steady pace. If there is an exciting climactic moment, maybe you can choose a more extreme perspective for that spread?
As for the value study, I like the extreme contrasts; feels dramatic. Some might think it feels a bit too dark, but I think color will probably fix this. And I do notice how the 3rd to last spread is brighter than the others. Logically, this must be the climax of the story. But then the next spread is so similar in value and perspective. Again, try to vary the perspectives for adjacent spreads. Sorry for the long comment. Hopefully something here is helpful. It all looks amazing, regardless, but your work usually is.
