#1 Shot vertically, and with correct WB.. it would have been a nice image. As it is, it is a good memory snapshot... nothing more. Cute kid!
#2 cute shot... lighting is ok for what it is. If you had been a little farther camera left, we could have seen more of mom too.. her expression looks like it would have made for a nice photo.
#3 Cute.. but too much head and chin missing... there again, shoot vertically for shots like this, unless you have a specific reason not to.
