Heres my opinion.
First one: Eyes and skin look good. Generally skin color and contrast too. But some things looks strange to me... fo example lips... their's perspective looks bad... also the teeth dont fit.
Second one: Better then previous, but here lips looks strange too... on the original foto they dont fit to image (they looks like was badly added to photo), and after your's correction this effect goes even stronger -> top one is even more not realistik than bottom

.
Except that, generally good work.... they looks a lot better than originals.
