Cool! He looks great!
But why do I think he stretches too much that causes his lower-half to look awkward during the flip kick(or whatever you call it)?
I love the animation, it's so smooth.
The only thing that bothers me is that Sasuke's skin tone looks a little too dark.
I don't like Naruto as a series too much and Sasuke as a character even less but the sprite here really looks good. As people before me have already said the animation is superb.
Blind Sasuke Rocks XD!
