Good, a little art-schoolish
Its always refreshing to see someone mix non-digital mediums with flash, and the very well designed, pencil-drawn robot looked great against the gray cardboard background. The head-spinning and the missile pack fun elements too.
Still, you can tell just by watching it that it was made for an art class. By that I mean to say that you cared more for the artistic medium than the character or the story: "Okay, we have a robot trying to escape a cardboard box. Oh look he's doing some funny things to try to get out. But why do I care? What's his story?".
Yeah, its unfair of me to expect that sort of thing, but you get where I am coming from right? Still, its worth an 8/10 to see pencil-drawn characters every once in a while.
