Wow! Great Work! Since almost everything positive has already been mentioned in these comments I want to adress two editorial problems:
1. The Pregens seem to have some mistakes (I'm not really sure since I'm very new to the game, so it could be a misunderstanding on my part.
1.1 All the Characters have only 2 signature Assets at 6, although the book says that you get 3 at 6 or 2 at 6 and 8.
1.2 The Characters don't seem to have Limits anywhere on their sheet.
2. As some have already all atwork is very low resolution. And it seems that if text is overlayed on the artwork, it becomes the same resolution and also becomes unselectable. This makes smaller text almost unreadable.
Interestingly, all the text in the chapter "A World of Dangerous Challenges" seems to be fine. Maybe this is a clue. You seem to have done something differently there.
