I think Aerith's are the least worst, maybe due to her angle? Her nose is the straightest, which is good because I can't think of many nose that extend that far that also curve that much (but, hey, my memory sucks), and her lower lip doesn't stick out as much past her (relatively same-sized) upper lip (typing this while be a person if closer proportions to the other two). The eyes, though, while being a decent size, seem to be spaced rather far apart, especially considering the increased size of the other features ("normal" animu nose sizes would have similar distance from their eyes, but a larger nose makes the spread more apparent, if not wider).
But, there's also a few other outright noticeable subpar-ities, and that's to an untrained-in-proportions-and-other-artsy-crap eye.
