Not sure what the motive was here.
It's hard for me to take a work like this seriously without some background on the author. It doesn't seem to do anything with the topic of suicide. If you were looking for something extremely emotional to tinker with, you found it.
It was all well drawn and I like this kind of animation (within the context of its execution).
My own opinion, I really liked the girl. People who mock individuals who are suicidal are extremely shallow. One thing you can say about the girl is that her relationship was obviously very important. You can't give that credit to 80% of people today.
