The more comprehensive gold manuscript critique is an excellent option if you want what I call “story mechanics diagnostics”. Basically, it’s an in-depth look at how the developmental elements of your story work together at a chapter level.
At the end of the comprehensive manuscript critique, you’ll receive an editorial letter (i.e. the global comments as in the silver critique), and a separate Revision Notes document which has an analysis of what works and what could be improved in each chapter of your book, and how those pinpointed elements contribute to the overall reader experience.
Note: Authors I’ve worked with in the past like to keep a copy of the Revision Notes next to them as they work as a “revision cheat sheet”.
