ok i took a look at the others, and i have to say i liked yours the best

i just want to re-emphasize my #1 comment again, even for the small things. like for example you had quite a few scenes where you showed lots of user little faces visiting the person's site. i know it sounds silly but i really enjoyed those little scenes, i would just advise you to try to perfect the timing so that the audio matches with the video as good as possible.
comparing your entry to the others its very clear you spent a lot of time on the animations - in my opinion it was well worth it - yours is much more enjoyable to wach than the others!
