I like the "Uryu" element (imagine, fifty Narutos lined up in formation, blasting away with chakra-ya; devastating)... I don't like how Naruto had an overnight maturation. That kind of thing doesn't really happen, even in anime...
BTW, there's another way to say "shoot to kill", which I'm assuming you got from Bleach. Ichimaru Gin's shikai uses this phrase: "Ikorose". I just thought you might like to know... I think that it's a little less of a mouthful, if you get my meaning.
This is really original, especially in the way that Naruto handles situations. Most people would have him charging into Haku's Mirror Jutsu, but you have him pulling Sasuke out from below, which (now that I think about it), is absolutely genius. A design flaw that Haku completely missed, apparently. Too used to fighting on solid earth... Brings up the question about what he would do against a Tsuchi-nin that burrows...
Anyway, keep up the updates!
