Nothing too exciting.
I find the joke lacking a bit. Also the long conversation before the joke was kinda boring. It made the movie less watchable. Your animation was pretty decent, along with the drawings. You also could have changed the voice a bit between characters, because I thought for a second the mouth was missing on the mushroom.
Next time, you don't have to bash people just because they are on the internet. If someone didn't have a life, they would be dead.
