The fabrics your are using for this are so beautiful! This quilt is going to be stunning when completed and I have a feeling no one but you is going to notice a few chopped points. This quilt is on my bucket list but way down. I have the book as well so I am going to take a look at it. I'm wondering if this might be easier to PP? It shouldn't be too terribly difficult to draw out the units for PP. But it will be a time consuming task if you have no way to photo copy your pattern once you get it right.
On your second picture I see you don't have any seam allowance showing on the two units that are not yet attached to the Square in a Square. Are they folded under or is that how the unit is coming out? Or am I mistaken and they are attached and you are doing set in seams?
