Great animation, lackluster voice acting
Your animation and backgrounds were fantastic, but the voice acting was lacking, especially the maniacal demon laugh, but hey, that's kinda hard to do for most people anyway. I agree about the anger thing. I haven't read the book, but the word anger has a much different conotation than the word wrath, plus, it's not really a sin to get angry, but seeking wrath is often quite evil.
But I don't know what that kid was talking about when he mentioned a ball of energized mass as God. First of all, if you want to personify God, it would help to use a person. Also, who's to say what God looks like. I personally like the black God, it was a nice touch.
