The first 4 face Daily paintings

Well, I wonder where these came from? I like them today. I can see flaws in the features but that should get better the more I paint. What do I like about them.....the faces, the lace, the lack of colour I like better, the jewellry.They seem interesting, calming, pretty, vintagey. How could I develop them ?
Do a different coloured background.
Do a landscape background.
Change the position of the faces.
Try different sizes of figures.
Try a whole figure.
Carry on.
What are they about ? Don't know yet.
