a hint
nice pencil animation, i will suspect that you already know this but your walking/running on your first 2 caracters is a bit off... the walking on the later caracters is spot on.
its actualy nice not so see any color in this flash. so good job with that.
your talking is perfect.
and your speed is dead on. the only this that could ever change is teh fact that there could be a simple line on the ground to show over all motion.
your work is actualy very well done... keep at it. and i know that anything that you do will go straight to the top of th portal submissions. :O)
