Well written but imbalanced.
I really enjoyed reading the in depth ancestries descriptions that hit all the hallmarks of Paizos new standards (how people might percieve you and how you might feel as a member of this race). However, while it gets the formatting spot on, several ancestry feats are flat broken, including giving aasimar a level 2 champion feat at level 1 which is doubly broken and likely a poor inference based on the bestiary.
All in all, its a good guide line to fill in the gaps until aasimar and teiflings get a first part conversion but it needs some strong arm home brew errata.
