The sound is pretty good.
I like the animation; black line over the brown background, really simplistic but that's nice.
The line work, which looks like a sketch matches pretty well the feeling you are trying to communicate.
The drawings however don't really give my this feel. I get that it's your style but I find it a bit too finished and cute for what you are doing.
The black transitions look pretty bad. They don't match the rest of the video in my opinion.
I think your work could really improve if you start improving your artstyle and try to be a bit more free, at least if you are trying to make experimental videos. This is the kind of videos I've seen countless times and labelled as "experimental". Your video is not that original, that is mainly why I'm giving this rating.
