As the self-proclaimed foremost expert on fairies with countless hours spent perfecting generating them, I felt the need to check dis out :3 The primary things it seems to add is a more uniform style to the fairy wings (most models have different variations in the results) and some specific clothing styles. Overall I'd say it's pretty decent at these things, though I can't help feeling like I'd want there to be more to it. That being said, the outfits are good enough that I'll likely be using this to help with that.
