@rachy Your thumbnails look really humorous. I know that eager feeling of wanting to jump right to painting, but you're doing it a better way, with lots of planning on the front end, to save time and fixes on the back end.

The way you've organized your thumbnails, though, would benefit from a traditional storyboard structure. Here's an example of one I've used (that Lee White might have shared in one of the SVSLearn tutorials):

By using this structure, you'll be thinking of each spread layout, and noticing the pacing and progression more. This book dummy layout is for the standard 32 page book, but other standard lengths are 16, 24, and 48 pages, so you can modify it as needed.
