Depressing
The animation was well done and the idea was easy to recognize. However, although the animation was well done, I found several things lacking:
1. Way too much blood. I understand that this is a poor homeless man but is all the gory detail really necessary? Personally, I think it only takes away.
2. Very depressing. Whether or not you intended to depress people who watched this, depression is a very annoying emotion to deal with and normally makes viewers more reluctant to watch the flash over again or any further flashes done by that author.
3. More content. This isn't bad but I think you could take it further.
One thing I really liked was that everything was completely understandable without any voices or text.
