I liked the way the animation looks,
I also liked the way the mouth flaps are properly synched instead of generic ah-buh flaps, and the character movement is smooth and stylish which already puts it ahead of a lot of other internet cartoons, but skills like yours are wasted on stolen, unoriginal audio clips from the wasteland of pop culture.
it's not hard to find amatuer voice actors with good mics and burning passion for thier art. and here's a shocker: they work for free, and some of them can probably do pretty good impressions of naruto characters..
sure, it's naruto themed and all, but you can maybe change it around to be more of a parody, but put actual thought into it. come up with your own jokes. maybe make up some characters, and write a script for them and animate the result. because there is something that can be funny with a narrative, instead of interchangable jokes where one thing leads to another with no connection to a coherent story.
The animation is hilarious, and the audio is nice and clean, but it's not yours. well, you drew it and put it together i guess, but in your next movie, do yourself and everyone else a favor and do not settle for mediocrity. i'm sure you have an imagination. we all have one. but if you find yourself low on creativity, maybe stop looking at the idiot box so much, and work more towards what you know.
Good luck on your next work, and maybe you'll even make something i like. not that i didn't like this, but i put it in the same category as phoenix wrong, and that doesen't feel right because you actually did some work for this, even if the sound's not yours, and neither are the characters.
for ninja, they sure do a lot of standing around doing nothing.
it's like the original in that matter i guess.
