1 - It looks a little soft maybe because it was shot at 1.8. A little too much space at the top of the image IMO. I don't mind selective color but the eye color doesn't look realistic. Try adding some contrast to the picture.
2 - Cute but the house in the background distracts from the pictures
3 - Another cute shot but too much space on top.
There is a road/driveway in the background of #2 and 3. Watch your backgrounds!
Very cute little boy!
