This is Easily your best serious animation!
As much as I loved Die Dame En Weiss with it's clever use of shape tweening; this was much longer than Love and Gone, as well as better produced. It may not be cutting edge to the point of overdone, but enough to get the point across.
Animation: That was pretty good for something done in two days. The use of silhouette was a crafty choice in my book as they were well animated and very expressive. The only flaw is that the walk cycle at the last part looked rather choppy.
Sound: Finally, you found an Audio Portal song that actually fit the animation. Even though I appreciated you using one of No1r's songs in Love, it didn't fit. This on the other hand, fit the tone and animation perfectly. Kudos for not having any voices for that would have ruined the overall mood.
Content: It's original and I liked the whole interpret the story as you see fit angle. (I'm working on one of those myself.) Also, I approve of you also doing a flash that sets an atmosphere rather than telling a story. Something that few others have tried, but only one or two succeeded in doing so. Not to mention, the filesize is small enough for those with slow connections.
What I extol:
-Great use of silhouette animation
-Nice song choice
-Great direction and timing
What I disapprove of:
-A bit too fast and too short for a drama, but that won't hurt your score.
Overall: Here's a ten out of ten, and I think a lot of people on here could learn something from this very flash.
