I was agonizing over a recently dead character's reincarnation and this pdf came to my attention by way of my spouse (who was also GM for the game in question). It fit the bill perfectly, and here's why.
Fluff: Well, the fluff went out the window for my newly reincarnated character. And I'm sad about that, as it's very good fluff. I especially like the fluff for the Piper, that being the race I reincarnated my former Human Cavalier to. She's now a Cavalier/Bard.
Crunch: This is where the product goes from 5 stars to 4 for me, and possibly for a silly reason. When poring over the text, I was hoping to find age/height/weight tables like those found in the Core Rules. Having a description that reads out the race as being built similarly to an existing race, but smaller, didn't quite fit that need.
Art: I agree with the previous reviewer on the matter of 3D rendered art. The first bits of art in the book are great, but it slowly goes downhill. Now, that said, this is the sort of pdf that could do with very minimal art and still be good. Thus, it's STILL 4 stars.
Proofing: Only one typo that caught my eye. That, sadly, was on the first page. Hale instead of hail. But easily overlooked.
Overall: 4 stars. If you're looking for something off the beaten path, this is the place to look.
