DSX8, I really like how you rig, and I wish I would be as good as you. You can even rig capes and dresses perfectly, and is what I absolutely like with your rigs. Tell me, how did you do eyed expressions? Things such as hurt eyes or Final Smash eyes, such as your Skyward Sword Zeldas have. I tried rigging them to their corresponding bones, but they don't follow the face when animated... Keep up the good work!
ima answer this for sake of speed.
you must rig it to the normal bone (neck and head bones) and in brawlbox, go to the object and on the right look for a option called visibility bone, open the thing on the right and look for the bone that controls said expression, also be sure to do the same with the main face, otherwise it wont dissapear and u'll have 2 faces at the same time, i hope that helped
the 1's i did for skyloft and goddess zelda.. those were rigged to the HeadBone since they were just eye expressions.
but ya if u do wat Jokekid said, it'll work for ya.
