First of all, I found the reading order confusing.

You've divided each 'chapter' into 8 frames, okay, nothing wrong with that. However, I started reading the top 4 horizontal panels first and wondered why it felt disjointed. It wasn't until I saw there was a thicker line in the middle of each chapter that I realised that I was supposed to read the square of 4 panels on the left before the square of 4 panels on the right.

EITHER: Have each 4 panel strip read horizontally instead of a square
OR: seperate each 4 panel square with a wider vertical gutter, about as wide as the one that seperates each chapter.
