Be bold, and show your fic! The worst anyone can say is just "I hate this! You're a crappy writer!", amd so what if they do say it? There will certianly be other people on the list who will enjoy it. No group with 1000+ members is going to share a universal opinion of what is good fanfic.

The members of Henneth Annun are just people, not deities (no matter how much some of them may seem to believe the latter). Don't be intimidated.
