Sugestion: There are several attachment points on your avatar, but in the face you have 2 attachmentpoint who are not in use ( I think ) namely the left and right eyeball.
When you have lashes, hats, fangs, piercings for exapmple, you can not attach them to your eyes and I think nothing fits there without moving.
There is nothing sillier than to see your nose piercing wandering over your face every time you move your eyes.
My suggestion is to replace the attachmentpoints left and right eyes into left and right cheek.
At least you have two more attachmentpoints which dont make your attachments move all over your face.
Its a small idea but you never know.
