1584285 I'd recommend you looking at a fic you like the sort of writing of and mimic the writing style of that to fit your story, just adding detail to fit it.

I have been having this idea of a human from the equestrian girls universe follow twilight back to the pony world. They end up liking being a pony and do not wish to go back. I been thinking of making it a ship fic with human trixie and twilight. Or any pony in general. I am not a very good writer so I do not know what to do.
