Nice execution for the ending. I LOVED the yoda visions, fantastic stuff. And great way to hint at Vader without showing it.
I see you you liked some of my ideas from above, looks good to see them being utilized!
My only critisism is that, can Leia be explained once we find out she is lukes brother, If I go back and watch the birth sequence, is it believeable that there still could have been another baby delivered? She Clearly dies, and there is only one baby that been delivered. What does everybody else think? Maybe after Luke is delivered, have padme screaming again and another baby (Leia) crying off scene while we watch yoda and let that be the end of the scene.
I love this forum, I love watching this stuff.
