The hardest subject
Story telling. People are merciless and brutal when it comes to story telling. Its hard to get a good rating in this area because you don't have to have just one good or funny idea for 2 minutes. You have to build a world, populate it, invent a backdrop, plot a time line, and then figure out the story.
I would say, in my humble opinion that you are off to a great start. Of course there are going to be people who just cant get around the rough parts in your story, but that is because they are used to being plugged in non-stop feel good entertainment. Your attempting something much harder than a two minute gimmick that makes you giggle. Animation could always use some work. Don't let that stop you from making more. Learn as you go. One main issue is that, while most of the script was good, try to spend a little more time on script writing. If you have a gripping script and the lines given are something that the audience has never heard before, or hasn't hear done like so, they will be much more forgiving if they are bothered by something else.
Keep up the good work.
