Excellent stuff
For me, your short movie was a nice breath of fresh air. The sound effects were clear and crisp, with the music complimenting it nicely and the graphics succeeded well in keeping the viewer's eye to watch out this short piece.
What brought it all together though IMO was how you portrayed the story: the style leaves you wondering if it's real, just a dream or something more (no spoilers here folks!).
Definately hope to see more of your work in the near future. Possibly some background story on this piece perhaps? :)
