As usual, a nice, varied and solid set.
#1 is the one I like the best -- which means that is really great in my eyes. The one comment about that one is that I would either prefer to see the first boy's only in shilhouette/profile (as we can see his brother) or with a slighlier brighter face so we can see his face better. Nothing you can't do in PS!
Very nice set. I guess it's not very easy to shoot a group of 4 including two boys?
Captures are good, and also quality shines. May I ask what camera you are using to shoot children? How long did this shoot take approximately?
Nice series. In this and your other work I've seen I've been impressed with your skill at mixing up the points of view with shooting distance and your eye for finding pleasing patterns and perspective in ordinary settings. Less apparent and equally impressive is the behind the scenes rapport you obviously establish with the subjects to get them to relax and "be in the moments" you so skillfully capture.
So cute! 7 is classic. Love the interaction you captured between parents and kids in 6. You have a nice timeless feel to your photography that your clients will be able to enjoy for many years to come.
