So besides the fact that you created amazing characters that people identify with and a universe that kicks ass and strikes just the right balance between reality and believable deviations you're worried. Seriously, everything you write strikes true and intruiges people into wanting more. You write vivid passages describing both items in the universe but also the personalities of those who live in it, and you doubt your talent. You're an amazing writer and I seriously hope you take it beyond fandom. Because this is amazing work and you shouldn't doubt yourself so much. We love pretty much everything you do and are excited to read anything you read. You got this right, you know you did.
