My immediate reaction: Doesn't do much for me, either as a standalone photo or insofar as meeting the challenge. But a nice close up of her eyes, and I'm sure she is a treasure to you (though not really a hidden one). Probably a 6 in the Eyes challenge, but just a 5 here.
Another one that I'm not sure works in the challenge. Also, it seems that her left eye is in better focus than the right. Perhaps a slightly deeper depth of field would have left me more satisfied. I know that you probably tried all different crops and who am I to say "you should have cropped it differently", BUT the crop doesn't quite work for me. With a shot like this, I might have tried to play with some brightness/contrast adjustments as well. I think it could have made it more dramatic. 5
Blue eyes are always mesmerising. Moms, housewives, grans are all treasures, often neglected and forgotten. DMC.
The shot is just OOF, and I would have used natural light in her eyes to emphasise that beautiful blue.
