I looked at the eyes pretty carefully with both the Joint Editor and the Setup room, and I couldn't see anything that seems amiss. Can you explain what's wrong?

The eyes rotate off-center, though that effect isn't really all that noticeable unless you rotate the eyes beyond normal human limits.

Sydney is also naturally cross-eyed.  By default, her eyes were manually rotated about 5 degrees outward to compensate, but the point-at function only takes the origin/endpoints of the joints into account.
