These look all right, although you probably want to let Elves keep immunity to sleep--since it's a part of their fluff that they trance, not sleep--and dwarves are MUCH better off with Stonecunning than the favored enemy bonus. It makes a lot more sense, since most dwarves would live out much of their lives underground, by the standard fluff at least.

Also, this belongs in the Homebrew section.

Or maybe not, since these are basically the 4e races. And by basically, I mean the human was copypasted from the 4e phpb.
