Come on...
Every scene was about 3 seconds long.
And next time use your own names, don't use ff music unless you are referring to a final fantasy game..
and the drawings you make aren't that bad...it's just that the animation sux. Spend a lot of time in making the characters walk smooth if you plan on continueing to make this movies. Then later on you can give the bullets/shurikens/weird grey thingy's some detail.
Ultimately, I advise you to think over scenes a bit more. U used a scene where we could only see half of the grey character while he took the 3 seconds to say one thing.... that's a shot for sudden anger, or fear, and is supposed to shoot into frame immediatly and dissapear just as fast.
Same goes for the other scenes.. the guy was walking. Make it easy for yourself, animate some cool footwear, and then let us see the shoes, followed by a cool, cold as ice , samurai face. :)
It's easier, and it looks better!
I think you can do way better if you just take a little time to think things over
