Over all, I'd say it's a good start.

I don't think Anakin needs the Force lecture until after he sees it in action. And when he does explain it, it should be shorter that the one Luke gets. Mostly, because they're in a hurry and it keeps the original scene special.

As for the princess rescuing them, it seems a bit convenient to have her as a guardian. Perhaps she was trying to escape - making her the coward and not her brother - and Obi Wan and Anakin unintentionally shame her into going back. If you do want to keep her as a forest guardian, then please, no white until the end of the movie. It's symbolic of her accepting her destiny.
