I love this image. Good job. I would change two things..first I'd mirror it to get a left to right flow and second, I'd change the color to sepia tones. Still, I love this image.
Beautifully done. Just enough contrast to show the facial features. The low contrast approach makes this very peaceful and the cyan toning suggests nighttime.
I like the tight cropping but not the color choice here. It leaves me cold. a gentle sleeping baby should give a warmer feeling. There are nice abstract qualities to the baby's face established by zooming in so close and I think you've captured them well, but that color cast hurts the shot for me.
This is my favorite of the challenge. The softness of the focus, the pastel blue shade, the peaceful, natural expression of a sleepiing child all combine to create a delicate work of art. I wouldn't change a thing. Good luck.
