It's very cool; but I'm wondering why you have Druid spells listed under the bonus spells, it seems like Bard or Sorcerer would be more appropriate with the high Charisma.

Really, my only issue would be that the class abilities give you a lot of Charisma and Dexterity, but nothing in particular (unless you're already a bard or sorcerer, which in fairness you probably are) to use with it.
You might want a smaller ability, perhaps a lesser version of Gambol, to use with the artsy rage.

This is really cool, I've always believed that the Fey are among the coolest thing in the D&D mythos, and I think this class really captures what a fey PrC should be about.
