What do you guys expect from an Evangelion Fanfiction?

Hello, you guys may not know this, but I am also a part-time Fanfic writer. Recently, I have been infactuated with Evanglion and decided to start a story about it. But since I'm both a newbie to Fanfic and Evangelion, so please be honest and tell me what do you guys expect from an Evangelion fic?
