First off, I like the new races and associated rules overall. I just want to make one small comment:
I find it a bit odd that Humans get an ability called "Skilled", which gives them more skill points, and Half-Elves get an ability called "Adaptability", which grants the Skill Focus feat.
More skill points means having ranks in more skills (since you can't exceed your level in ranks), which makes you more adaptable and flexible. Skill focus makes you better at a single skill, not adaptable. I'm not disagreeing with the mechanics, but I've always felt the names should be switched.
Cheers
