Moderate exterior
I can see you're trying to make viewer ponder about the downfall of the world, but you're touching only the surfaces(even that, barely). Destroyed buildings and corpses tells very little. The poster too fails to raise anything beneficial to think of. I would like if these part are extended, deepened. Make flashback of how and why these things become what they are.
I also noticed there's no credits for the music. Isn't that the Schilinder's list theme? Possibly by Itszhalk Perlman .
Proper credits. Deeper cuts, not graze on the skin.
