C&C per req:
1. Your light was at least one stop too hot, and you really need a reflector image left back to bring out a little detail on the child's right side. As well, your DoF is insufficient; for an image like this the whole face should be sharply focused.
2. I'm afraid I can't find the point of focus in this image. Why such a low shutter speed? Same comments as per #1 for lighting.
3. Okay, this image in particular tells me that you don't have a firm grasp on the concept of depth of field. Spend some time learning a depth of field calculator like this one to learn what apertures you should be using.
4. As per #3
Just my $00.02 worth - your mileage may vary.
