well...

awful. terriblre.

welp...

the only real problem i see is an overlap of sprite frames. As for sleepy turtle's comment, don't worry about that. just tell him to look up the sprites for noob and he will see that noob IS just a recolored ninja in the old games. The animation seems to flow smoothly. Just the overlap is the problem. Other than that, you've avoided a lot of pit falls of new sprite animators. Just be sure to add a preloader next time. they are downloadable from the downloads section and it takes two seconds to put it into the movie. Other than that, it was pretty good. Assuming this was a test animation.

a failure of epic proportions

if i could i would give you negative stars....thats not even noob saibot...its just scorpion rendered completely black...if your going to claim it is noob saibot make sure he is using his attacks, and not scorpion's signature move

what?

a) your sprite animation could use some work
b) waaaaaaaaaaaay to short
c) it loops
d) "GET OVER HERE!"........... really?
e) it's not even Noob, it's just one of the ninja entirely colored black
.....must i go on?

too short and useless.

this was really boring,
there is no play button, and that was very short.
nothing more to say.
