First off, could you please change the colors of the font? It's rather difficult to read red font on a red skin.
You should also remember that hitting the Enter button twice creates a new paragraph online. So when you want to create a new paragraph (when someone speaks, or when changing subjects), that's what you do.
That's really all I can see so far for suggestions on your story. Like I said, it is rather difficult for me to read the colorful font.
