I'll give you 2/5 for the effort that was put into this at least, but this has problems:
1. If you really want to work with stop-motion I highly recommend you use objects such as clay, legos, or anything that can move its arms and legs around. Using random objects that cannot move anything around isn't really a good idea. It's all about giving the illusion of your characters being alive.
2. Try to get a microphone for voice acting instead of just using written paper for dialogue. Or at least try to get voice actors that can help you. There are plenty on Newgrounds that can give a helping hand.
3. I recommend swivel so your stop-motion video is not on loop. It's free so it should be no problem to get.
4. When it comes to stop-motion, it is very important to keep everybody out of the frames period. So if there is even so much as a human thumb in the frames, it will ruin the experience of the video. Unless if it's part of the story or something, there is no excuse for it.
5. Sort of a nit-pick, but the frames in the video are going too fast. Either add more frames to make the stop-motion smoother, or slow it down some.
Now don't think I'm hating on you. I'm only giving out constructive criticism because I know you have potential to make something great. Please take my advice and try to improve. And I know you can improve seeing the energy that was put into making this. Good luck!
