Final mock up on the presentation day.
Comments:
Overall it looks fine. It fulfilled the communication plan.
However,
the material is too fragile that it might cause people to be impatient when flipping the page to read the book.
The cover of the book is a bit too thick. It does not look appropriate with the thickness of the content.
Go for Japanese binding maybe?
Prioritise your intention;
Do you want the audience to read the content or just to have a different feeling towards the book?
This is the overall look of the accordion fold when it is being pulled out.
