The music was nice, it gave a calm, fitting touch to the piece. Well done there. The animation was also very good, nice job. It was a bit weird, but regardless, the animation took real skill to make.
Some improvements would be to make some parts a bit faster, like when you're starting back off with a line (when an image fades back into a line).
Other than that, this is a pretty good flash. Well done, keep up the good work!
