MY EARS! MY EARS!
A bit of constructive criticism:
The story made sense to an extent
My main problem were small things.
Please color in the mouths. Although you can tell the difference, it just helps in the overall presentation. Watch continuity as well. Nobody likes a sudden irregular white border around the pc unless its being used in some weird 4th wall breaking joke or in some sort of way that makes sense. You can be random, but at the same time, you need to be smart. If you want to work on your animation, I suggest tutorials by Spazkidin3d on YouTube. It really helped with my animation, but do what you wish. I am only suggesting ideas to make you better.
Holy crap i didnt even relize the pc error. I think it may of had to do with the layer it was on -_- I also just found this guy for tutorials on youtube (lilredheadcartoons)
