I have to say, I like the video, but I would recommend two things to the audio to provide a little bit of mood to the story.
1) As the title screen fades out of sleep, have the ambient noise fade out, but not completely, the have it get louder to the point at which you begin seeing the character for the first time.
2) With the ticking at the end, make it grow louder and louder as time goes by after about 3-5 seconds of plain ticking.
