Absolutely gorgeous pictures and the little girl is so pretty cute. I like them all. For me the #2 stands out - nice composition. I like that ur pictures are not overprocessed looks very natural skin tone and beautiful colors.
I like #1 a lot, but if I were that baby's mom (and I am a mom too, so I can at least give advice as far as that goes), the print I would want on the wall in my living room would be #3. It's just simple, peaceful, beautiful.
