I guess you just don't understand the ? one.
The whole idea is that it looks unfinished and is on a different angle to the others.
I think that goes hand in hand with ? to be honest, but I'll do a more detailed one later.
On the Yus one, I was aware of the face being on the wrong angle, but I thought it fit the character.
I'll redo it using the old one as a reference.
Edit:
Done. It's a bit more detailed than the others, but I guess it'll do.
