It's verrrrrrrrrrrrrrrrrry interesting, to be sure. The transition from Obi-Wan's hut to the Tantive works for me because I get the kind of editing you had in mind. The cut from the Tantive back to Obi-Wan, however, is too rough in my opinion. It almost seems to indicate that Obi-Wan and Luke were talking while the Vader stuff was happening, which counters the flashback feel of the whole Tantive scene. You should fade between them or something instead of just a straight cut.

Also, when we first see the escape pod launch at the very beginning, it's unclear exactly where it came from (the Tantive or the Devastator). I'd include the shot from the flashback of the pod leaving the Tantive.

Very interesting project, I look forward to upcoming clips and the likes!
