Dark room- Double Exposure

How did I create this image?
I exposed my background first, which is the shadow of the tree.  Then I put my exposed sheet in my drawer and put the second negative into the enlarger. After the teststrips I pulled out the exposed sheet and exposed it again. This time with the other negative and then I developed it and this great contrast was created.
Do I like how it came out? 
Yes, I like it for sure. The contrast between the branches and the girl with the dog looks so great and it created an very interesting picture.
Where is my focal point in this picture?
I'd say it is the shadow of the tree/ the trunk of it. It is the darkest point in the whole picture.
