You're almost there, just a little further!
Animation wise, this was either great or poor. There were some parts where the characters moved naturally and it looked very realistic, but there were some parts that were very poorly made such as when that one person is lying on his back and reaches with his arms up there was no animation for the clothing on his arms.
Story wise, absolutely nothing was given away in the grand scheme of things and that's a real let-down because there's so much mood and tone in this.
VO work could have been better and it can be tough to find the right ones for each part but it pays to be picky.
The quality of the video (not the movie as a whole) was an immediate turn off and should be the first thing dealt with. You're just so close to being a very engaging narrative, just add that extra bit of polish and you've got something special.
