Im not sure what the story was intended to be, but what i got was that she was faced with judgment day in the begining, but when confronted with her sin she felt ashamed, and couldnt take responsibility for them, so He sent her to a form of Limbo? to choose either her own ways or Him. And she kept walking farther and farther away from Him until finaly at the end she was faced with a spirit of what she once was, and was tempted with it, at this point i feel like she might have given into the temptation and started a decent to.. Hell? But finaly repented and was given another chance to make it right. I feel like she ran at the end because she felt unworthy to return to Heaven even though she had taken responsibilty for what she had done, and was scared to face Him again..
Anyway, AMAZING video whether im anywhere close to right or not, the art was phenomenal, and you should be very proud :)
