I like the third one. The background and the color of her dress really makes her pop
the first 2!
The pink ones! They pop more.
The top one, I think it has the most contrast around the face/hair area, which is the focus of the piece. It gets a tiny bit washed out in some of the other color-combos. Plus I think the pastels just fit the mood more. :)
