This is wonderful man, so far been doing westfall quests and have yet to notice a bug. I noticed you plan to work on adding animations to it. That's about the only thing I could imagine you doing to improve the immersion.
the unknown area is actually a scrapped azshara 40 man raid. Took place within the dead body of an old one. Was going to go alongside the large scale AV like pvp zone they had planned for azshara.
