Nice job on the new opening sequence. Since you included the crawl and all that, I'm wondering if you changed something there.
The firefight between the blockade runner and star destroyer is a lot more impressive now. It's amazing how a few extra laser bolts can add so much.
I liked the first version of the Tantive IV explosion (although it did look a little like it was originally a circular explosion that you distorted). I loved the engine shutdown in the second version.
Having the Tantive IV lose stability for a second is an interesting idea, but something about your footage seems a little off. Maybe it's the perspective.
Personally, I think the best thing would be to have the explosion, camera shake, and engine shutdown, but no loss of stability. Remember, we see 3PO lose his balance slightly, not fall over.
And here's another idea I just had: When we see the Tantive IV being pulled into the star destroyer hangar bay, the camera is fixed on the Tantive IV. This has always bothered me, as it gives the impression that the Tantive IV is being still, while the star destroyer "parks" over it. Can you alter the shot so that the camera is fixed on the star destroyer as we see the Tantive IV moving into the bay?
