I think if you were to increase the length, increase the Frames per Second, and increase the content in general, you might start getting some better reviews on each video. For example, if this animation were to include a man or woman purchasing a burger, sitting down, unwrapping said burger, finding it had a face, and ending it with a scream, people would be more willing to rate the video higher. Four seconds of choppy animation just won't cut it for most people, especially if half of that four seconds is "Created by me, share it, pls respond."
The humor in this video is certainly there, and if it were embellished people might start paying attention.
