Wow!! This is awesome, nearly perfect!!! It looks like oil painting ! You remind me Though Kojima (Castlevania) !!

The Good: Every piece of the pic blends well with each-other and the general composition. I can see a general line of direction from the bottom to the top of the pic, and yet, almost all your characters are looking/acting the other way. There is a quiet harmony, despite the "war atmosphere". You put many various elements (humans, animals, archicture, flowers) which is really beautiful. The colors are marvellous, as they're not flashy, and keep a unity throughout your illustration. Your human anatomy is almost perfect!
I love the way you treated the background. As a ghost appearance (and fitting to Zabuza's jutsu). It allows us to concentrate on your central elements without destroying the image, without breaking the harmony you've created.
I don't know or remember the meaning of the flowers (I love the way you managed them), the birds nor the building, but I assume you put draw them on purpose ? If it is, well done, because on the concept you'd completely masterize your illustration! And the little blink with the rabbit is lovely.

The less good: There are only a few. First, about the almost perfect anatomy of Naruto, Sasuke and Sakura: Naruto right eye is in a wrong position (should be the opposite), Sasuke's forehead is a bit too big (since you're on a tilt-up, it should be the opposite, again) and Sakura's knee is too sharp, and the way you articulated it is a bit weird. Look on people knees, ask them to pose, and compare. Maybe seaze the opportunity to make some sketches. Oh, I've just noticed it: Sasuke's missing two fingers. I think they should at least stick out a bit. Oh, and Kakashi's left knee's sticking out a bit too much.
A detail that bother me about Haku. It's rather strange how she's included. See, she appears behind the birds and the flowers, but then disappears behind Kakashi's legs. It gives the impression she's cut. Maybe some hair waving in the wind as you already started to do would fix this.
And finally as a Naruto fan, and a Kakashi fan, why did you draw him at his anbu time ? It doesn't fit to the timeline of the chapter.
Then I wonder why you put the Sandaime Hokage in the picture (I think you did for a reason, I'd like to know it).
Just a detail weird, but maybe it's normal: the tribal on the top of Naruto. I think it kinda breaks the style you put in your illustration. It's a contrast between your sweet style and way of operating the colors, the line, the shades and a simple shade without details. I don't know. On the other way, it goes along with the sun. Maybe a bit more transparent would be perfect ?
And why on earth did you called it "Naruto lolol" ? It makes me cry of despair. Your illustration's almost perfect and you "lolol" ? Aww, I feal so weak, I gonna faiiint..

Anyway, good job !!
