Not bad.
I've gotta say, there aren't many Naruto parodies here on Newgrounds so that's a good thing that you're starting posting this. Anyway, I see that you really can draw, some animations looks better than others and it looks like you didn't have much time or you just rushed this one through.
It was a pretty okay fan flash with some randomness but I would like you to watch some other parodies of Naruto here on Newgrounds to get some more inspiration.
Also, try using more frames and animations since it will be more enjoyable to watch instead of watching a guy's mouth only moving which is very boring.
