My favorite is the one of her smiling, and would move it the center. The one of her looking to her left, I would show as the 1st. and the 1st. one would go last.
Just my opinion, this looks good too.
More important; good light, pp, focus, expression, etc.
I think that titan's line up might be good, I like the smiling one best too, but I can see why it is the way it is. Baby pic is beautiful, not your typical expression, but that's what they're like! That kid will likely sleep with the same expression in 10 years time.
