Good luck with everything!
I submitted my second costume (a generic Mirialan Jedi) in almost two weeks ago. I haven't gotten an email or anything yet from Rebel Legion. They just updated their judging process, and local applications now have to be screened by a Kashyyyk Base Membership Officer, before they are sent to the judges' queue. Maybe that's why it's been taking longer for them, perhaps working out the kinks of the new system.
