This is a good observation. My take is that this picture is showing a guardian angel watching over the children. Who is known to nurture (not to be sexist) over the centuries – mothers -women.

Also, many artists are trying to project beauty in a subject and not to be bold – but we are pretty beautiful. Kidding. Artists for a long time have associated beauty with the female form.

However, as a woman when I think of angels I always think of Saint Michael. I want a strong angel that has your back when you need him!
