I have to say that this is a pretty typical Naruto fanfiction plotline. That doesn't mean it's not /good/, because, of course, many of these are. But they all have their problems. This story threw you right into the genin exam. If you had never read Naruto before, or, really, Naruto fanfiction before, you would never understand what just happened. Also, you should probably add some more detail. This was... rushed, to say the least.
Hope this helps!
