1st animation "Alien ad Soul"

The thing is I made this anime for my animation exam... it's not very good but I tired my best... The story is... one young man is drinking alone in the park at night. He's heartbroken. In that moment there is a mysterious shadow come to him... It's an alien!...He wants to eat the young guy but suddenly something is coming out from the guy's mouth. The alien is shock and afraid of that thing and run away. The soul (the thing that come out from the guy's mouth) turn to the guy with the confuse face like "why he has to run away?"
