A minor criticism (and if you're not done mixing the sound then you've probably noticed already): when Ben says "run, Luke", Luke appears to be reacting before Ben has finished speaking. I'd be tempted to bring Ben's line forward a tiny bit to give Luke more chance to visibly react - IIRC Luke sort of ponders this a bit more in the original version (but then, I've not seen it for a long time so could easily be mistaken).
