This is actually a good idea there is a sword that fights by itself on the hive why not a bow? 3/5 because the bow is the original one and it just looks like you took out Sylvanas and added some fog. Edit: As I said in the mage model be more creative and change more about your models for example in this one you could have added a few things to make it appear more ghostly, like adding spooky hands holding it or modifying the bow more, like making it translucent.
