The ruler tells me different. It's not the eye, but the shadows around the eye.
Yeah, the eye itself is fine. I believe it is the eyebrow and the sharpness of the nose on the right side that's throwing you off. The position and rotation of her face might also throw you off.
Some more C.C is that her right eye is lower or it appears that way.
Again, eye shadows. The eyes are aligned.
Doesn't appear to me that way.
