I love it! I really like the introductory text and the method to use two D20 as a D100 alone made me go WOAW :D
I do think calling one table the Focus table when the game has a Focus mechanic is a little confusing. I don't have a better suggestion though. Also you the Descriptor table has the heading DescriptION. And I am a little unclear which combination of tables I should use when. I think expanding on that with some examples might be useful?
Also, if you're interested in making it look a little more like the original book, check out the digital extras and the "GoblinExtras_playbook-instructions" file. It contains colors, font choices and more...
