The first photo looks perfect. I love it. The colors pop; her expression is dyanmic; and her eyes are emotive.
The second photo is too dark. The third photo is too gray and washed out (a problem I was having myself with a roll just yesterday).
The fourth is overexposed, and I realize this is probably what you were aiming for: that "angelic" look, although personally I find it a little cheesy. It also looks out of focus.
The last one would be a perfect photo but that tree in the background ruins it for me.
I would like number two if the baby had a lighter skin tone. Her skin blends into the trees behind her. On the other hand, her skin tone is perfect for photo #1. A Caucasian baby would be brightness overload.
