OILPAINTING old woman portrait black and white

A while ago I finished this portrait of an old woman. I found the photo on the internet.
The woman is suffering from Alzheimer and I was struck by her eyes.
You can see her confusion, not understanding.
I try to catch her expression with painting her in black and white. Her world is I think without colour, without details.
I hope you feel the same as I do.
This portrait is 20x15cm and painted on an MDF panel.
It took many many hours and I love to paint all those creases and folds of het skin.
A real challenge and I learned a lot.
