Great video, as always. But since you asked for feedback, here are two comments.
1) The priests and the children of Israel passed through on "dry" ground, not muddy ground. In the video, it's wet-looking ground, and you can hear some suction noises as the actors walk. That's the kind of thing my seminary students would get distracted by. (And the dryness of the ground makes it an even more powerful miracle.)
2) It's like you spliced two talks of Elder Bednar's together, and the voices are mastered at different levels -- with the 2nd and shorter one sounding different enough that it would be easy to get distracted from the content of the message.
