Not bad
It's not bad and is a good concept. I especially liked the beginning parts, but then I noticed the quality started to decline. First of all, make sure to stick to the same theme of music (relaxingly spooky). Also, perhaps don't use stick figures because it's sometimes hard to see what's happening, such as with the sexually oriented scene. Finally, you should have expanded on the stuff that happened to the guy when everyone thought he was dead. Rather than just focusing on his girlfriend's betrayal, you could also show other stuff that happened that contributes to his decision to commit suicide in order to make that decision more realistic. Like maybe show that his archrival gets his job or something like that or maybe his friend steals his novel manuscript. Anyway, you've got a good concept.
