Do you have any idea what the premise of your story is? Sure it's about a vampire, but what's the plot? What's going to
happen? What's at stake? (ETA--pun not intended.)
I honestly can't write a story unless I have at least a vague idea what's at stake, otherwise, it's just a meandering bunch of nothing. People talking, nothing really important happening. I think this is the problem with a lot of people new to writing longer stories. They get started, then, realizing that the story has nowhere to go, fizzle out. They don't know what their story is
about.
You don't have to plan the whole thing out ahead of time--I know I don't, and I write VERY LONG stories--but it's best to have some idea where you want it to
go.
Don't worry about it being cliched for now, just pick a premise and run with it.
