The initial idea seems interesting, the three stories do not met my expectations. They all share two problems: they are too slow, and they too abstract or complex.
The first story is too weird. Maybe more background music, or some explanation may help.
The second story was a bit appealing. The "Saw" stye idea is catching. However, it nfinishes suddenly, and I did not manage to understand what was your intention... However, I think that this one has great potential, and may be expanded as a stand alone work.
The third idea is too simple, and you seem to let the music "do the job", without enogh explanation of the story.
