I played through these last night. Generally quite good. There are a few harmonies here and there which I don't quite agree with, but that's just a matter of preference. There's certainly nothing "wrong" with his choices, they just are not quite what I might expect.
The one real quibble I have is that the set is laid out alphabetically by title, yet eight of the twenty selection require 6=D tuning and these are spread throughout the book. So for someone who wants to use this as a Gig Book, you either have to re-tune frequently, or re-sequence the pages. I'd have suggested using the concept of the old French lutenists, and grouping the titles in the book according to tuning needs.
Overall a very nice collection.
