Ok.
my concern is your will to pump out an animation in one day. people dont want to watch them really unless they have had effort put in. this is kind of spammy, and there is no power behind this work.
to improve may i suggest adding colour next time as their was nothing keeping my eyes on the screen, AND if the character is the same colour as the background it is difficult to focus on what the Creator wanted you too. your camera angles where enough to establish the content of the peice, however i only knew where the scene was SET at the end, when the plane hit. Perhaps add clouds or sky to aid the viewer in the acknowledgment of this setting. also it lacked a point. it is physical comedy i understand that. but you have not enforced the idea behind the comedy with perhaps enough tension. its length is upsetting. I found that before i realised what had happened, it was over. TENSION is always good. It raises questions... and what makes peoples jaws drop is when the question is answered with an unexpected answer. this is one take on comedy anyway. I congratulate you though, for getting through an animation, this is another step towards getting better. i warn you for next time though. PEOPLE are harsh. and really you should only submit content you truly feel proud of, or you know you have worked on/ For instance i can tell you have not really tried here, or at least tried your hardest. to improve you need confidence, and people will knock it if you continue submitting poor quality animations. NEXT time... Seriously think about your Animation. thank you for your time :D PS. ONE STAR FOR IDEA.
