This isn't done yet, please keep working on it.
1. You need to show the rest of the characters, otherwise it will just seem like a "Naruto by himself flash" rather than a "Naruto" Flash. You get it?
2. Put some coherent jutsu in there and prove that you are REALLY a naruto fan, not just some cheap image-thief.. (You know, with the hand-chakra?)
3. Make naruto say "Believe it!" and have another character punch him in the face. Just for a humor score. Seriously, this flash as it is now? the only thing funny about it is the lack of effort.
