The footage is effective--I like the choices Jay has made here. It all seems to tie in well with the idea of Jay's original text object. Attribution can still be given.
I can't think of anything that can be added, or even removed. As I have stated below: I like that there is no sound, and think the pacing/flow at this rate forces the audience to really think about what they are seeing without the distraction of any added sound.
I think the imagery is relevant to the story, and is my favorite so far (besides the text portion, because that is what introduced me to the storyline).
I like that there is no music. I don't think there needs to be any, simply because the imagery is enough, by itself, to make the audience think about what they are seeing.
I enjoy the fact that it is different, and not straightforward. It makes you think about the imagery, and what you are seeing (which I think delves into the entire premise of the story itself...so, it works).
