As you can tell, doing a full 3-D rotation of my Yoshi head doesn't work out very good. Blinking and the likes gets kind of weird because the "eye" seems to have no lid when viewed from the frontal position, but has lids when viewed from the back. I know that the way I draw Yoshi is three-dimensionally impossible, but that's OK. I'll just have to draw it differently every time I want to draw Yoshi's head viewing from the top down or whatever that isn't frontal view.
