It is way to short. Seriously you could only do a 15 second long video? There is so much potenial in this, and you have literally just shat on it. Where are the other three characters? Why are the lights not part of this? You could have one of them show up when the door is open, for something like a bell, or a chime. Seriously there is nothing fancy, or awesome about a teaser this poorly done. Take it back to your program, and add more to this. Till them. You have my ban vote.
