looks like a woman of southern Italy

Yes, she lives in Puglia

She looks a little sour in this photo. Is that her nature, or a trick of the camera?

Generally she is a sweet woman, in this shot looks sour because she's not very fond of being photographed

I think shes a very warm and welcome woman who can be very closed. I think she has seen a lot in her life and is a honest person whos very just/fair. She seems to pose just for you because she cares but she really doesnt like to be in a picture, i think shes too modest for that and doesnt see the use/need for it. I love this pic. She also reminds me of my own grandmother who unfortunately has passed away allready.

Thanks for nice comment Eladine, I'm very sorry for your grandmother

Thnx she has lived a long and overal healthy life and reached the respectfull age of 95. Many of us could be jealous of that.

Very expressive. Nice work

What sad eyes

A beautiful old face that lost it's beauty by over processing!!!
I would do the same here ( b/w , sharpening,to bring out the texture of her face )but i think you over did it here IMHO!!!

Updated

Much better Author, well done.

& now i can give you a nice vote author...much better indeed!!!

Lovely light and bokeh, I would crop quite a bit off the right side, into her hair, to make it more balanced and put more focus on the face.

Thanks Friiskiwi, I tried but it didnt make it better, in my opinion Nevertheless thanks.

You are welcome, it was only a suggestion, and it's your photo.
