Over on spread five, the left page - why not have the full sized panel first, then the detail? If you're going for the comic look, it seems natural to show more info before zooming in.
Some of these are a bit harder to go over - do have a specific order of works to follow? Must all works have some full-size representation? Some of the spreads feel like there's areas of negative space that can either be filled out, or further utilized.
It's amazing that you're doing this all on your own too! Do you have a deadline to meet, or does thing get published pretty much when it's done?
