Because while it's still not amazing it's at least somewhat passable and it's working out a lot better than the polydown (much easier to layer for starters).
I really, really, really should be doing separate systems for the body and the wings but I'll fix it later (as there will probably be something better to fix/redo it with later) but meanwhile fortuitously the edge transitions to skin will actually look fine as the child hairs from the top looks conveniently like fluffy down (sadly it didn't work upside down both ways I tried it but this is fine).
