Not very good. 2/5
It lacked a story, it seemed more like it was intended to be a prologue, however I do not think that in the context of this situation that will suffice for a high score.
The animation was sparse, you had a few drawings, and while they were okay I did not find them to be particularly moving. I also noticed that you simply used digital camera pictures of what is likely your own house, that is not animation or talent and I do not think it mixes well with the hand drawn work you threw in.
Try adding a story, some lines, better art work, more scenes, make something that isn't unsatisfying and lacking a story like this.
Perhaps some people were moved by the apocalyptic overtone you tried to create complete with sad music and people living in fear. I was not.
