Shameless self promotion aside, I do really like your elves. Their pretty close to the feel I want.

See my elves, rather than being the servants of other fey, have become their masters. They fled their dying empire on the material plane a few millenia ago, and have become the lords of a sort of mirror plane, basically a sort of space slightly out of step with the waking world. Their long estrangement from the natural world has effected them deeply. The Fair Folk are strange, unpredictable and often insane, and almost completely amoral.

Needless to say humans are terrified of the Folk, who resent them for moving into their old world. So elves as a player race are out, and the feel of half elves (often the result of elven depredations) is much different.

So stat wise, im thinking LA+2? A big bag of special abilities, but not so much that they couldnt gain class levels reliably.
