As usual the my two greatest nemesis with Koikatsu are its busted arm / elbow nodes and, in general, clipping - but always with the skirts. And they both come together, joining forces to make my life difficult with this set.
Wings are attached, loosely, to Pidove and Tranquill's arms, which should be functional and relatively issue free, but I haven't tested all animations. Unfezant, thankfully, has her wings in a normal location, but her skirt is way too big. Since she's effectively kneeling in her sprite (I think?) the skirt should actually be more knee-length, not ankle-length. So, I went with a shorter skirt. I think it looks better anyways.
Also, fun fact, I spent about an hour working on the hair going strand by strand in the meshes to tweak it closer to the sprite's appearance, then ended up throwing the whole thing out and going with different hair that required almost no modification (except removing a strand of hair). So yeah, that's always fun.
Enjoy!
