hmmm...nice work, but this movie should have...more.
i know its a simple walking loop, but you could add a:
-preloader, a play/replay button
-more action in this?
-a story?
and stuff.
say, did you draw son goku all by yourself? if yes, that's an EXCELLENT work.
if not, and if it's a sprite, then, you used it in a good way, tho it would be cooler if you drew it by your own.
all in all, your experimental short is good, but i would like to see more.
you have the skill, now you just have to use it more!
keep it up mate, u r good! :D
