What's that mean?

I think it's very hard to explain my feeling.
Because I don't like the black color in this pictrue very much.
At first it's just my fault to use the black color.
But I think the picture may be have some other meaning after I take a mistake.
Here is some power let me to keep on thinking about this painter.

Boy and girl? It's too simple.
The source of the baby? Also too simple.
Combination?

Um... I don't know.
