The presentation and layout of this book is exceptional, with plenty quality artwork.
The material is mainly revised from previous publications and versions of D&D, so no surprises here. We tried a few different races over a few adventures and they seemed slightly overpowerful. I'd recommend some further playtesting to iron out the kinks.
While there are 3 pages of additional feats it would hsve been better if they all applied to the races in the handbook.
