Only one comment?! This is so freakin cool! Why don't more people look at this! (And I'm so sorry if using too hard of words in my comments! English isn't your first language, so sorry!)
Seriously though, I love this. It's SO Naruto. Well, more of the 13-year-old Naruto because of the playfulness. I love his pose and expression. They're just so Naruto! (His expression reminds me of one Aang from Avatar would make, which is great because they do have some aspects of the same personality) The outfit is really great too! I could see Naruto wearing that, and I wish he would since his huge jump-suit outfit has always seemed so impractical to me, ha ha. I also like the things you put on his wrists (I have NO idea what they're called).
The coloring is also very nicely handled. It's so simple and yet so cool... I like how rasengan isn't emitting a very strong light, because that would've made Naruto look too intimidating.
I have just a few things to point out. His headband looks a little too thin, and I sort of wish his hair was just a bit longer. But then again, I like the short hair because it made him seem younger for some reason. Also, his shoes look like girl shoes! That's the only part of his outfit that's weirding me out a little.
