hmm...
Well, not much to say, just text and a minimal amount of animation. I hate people relating kh to naruto, tho. I think they're nothing alike, nor do I ever remember riku having an emo moment in kingdom hearts. Besides that, not much to say. Not bad, but there's a lot of room for improvement.
Next time, try adding in some kind of background, maybe some more shading as well. Also, when using the pencil tool, set it to "smooth" otherwise your drawings will turn out all triangular and pointy like they did here. It's not completely terrible, just not much to keep one interested. And doing anims about anime/videogame char. is a lil overdone imo.
