Write better fanfiction? Tips Please.

So I've recently started a fan-fiction story about Prince William and Kate Middleton and it's about how they met and their struggles and triumphs as a couple before they got married.

Here’s the story If Life Was A Fairytale

This is my first ever fan-fiction and basically, I would really like some help on how to make this story better. One point of conflict for me is the title. I personally do not think that "If Life Was A Fairytale" is the best title. What do you think? And what are your suggestions?

Another thing is, how do I make an awesome summary for the story? As you can probably already tell, I'm not too crazy about the summary either. LOL.

Should I make the story more detailed, less detailed, should the story be based about their families, too?

Please, any suggestions, any at all, please comment. :) Thank you!
