For the most part I liked it, you showed a wide range of skill sets. It wasn't overly long to the point of boredom. Couple of things seemed out of place was the use of some video, the shot of the sun through the trees, the door opening, the barometer, while I could tell you did some work on them, I would not trust the average producer to know the difference.
Also you used some footage more then once, specifically the glowy aftificial tattoo shot early and late and the video to look like misaligned tube camera footage, loses edge after the first time.
For a motion-animator, I would like to see a bit more logo animation, even if it's logo you made up or just text stuff, it may seem trite to you and easy, but people who hire need to see that stuff.
Finally, stylistically, you use a lot of blacks, whites and dark colors, I know that is "in" right now but in conjuction with the music, it left me feeling down. Perhaps that's just me.
All in all though very nice work, if we were in the market for a motion/graphics guy right now, you would definetly go in the pile of maybe's.
