I'm excited to establish these characters a bit more firmly, mostly because they have so many changes ahead!
A note on Anakin and Obi-Wan: as the great Plinkett Review made note of, having Anakin be an asshole from the start of the story manages to be both stupid AND boring. There are plent yof ways that Anakin and Obi-Wan can DISAGREE that don't devolve into outright hostility like in the Lucas prequels.
It's just plain backwards: you KNOW he's gonna be Darth Vader, so you immediately start 'foreshadowing' that. But that's childish. For his 'death' to MEAN something, Anakin must be a person there whose loss IS a tragedy. For their friendship to be destroyed, they have to BE good friends.
And when you know how your characters turn out AFTER a huge, *life-changing* event, you should make sure they begin differently than they end up.
But some things, at least, are constant. Whatever his goal or cause or purpose, Obi-Wan is - and always has been - a *liar*.
