Re: Z - A Fanfic
Like Hanako said, it was pretty good, You certainly have a way in doing battles, one of my favorite parts of any story. =)
Just remember that even though the characters in your story are the main focus, you should also incoporate your surroundings in the story. They are not in some kind of bubber so we should at least get a general idea of where they are (unless you want to keep it a mystery or something xP) in every point of your story. You mentioned they were in a stadium, maybe you can describe the cheering or booing of the crowd or the lights above the battlers. Small stuff like this can tell the reader where the characters are in a subtle way.
Good luck on the rest of your story. ;)
