Thanks for all the great feedback, both pos and neg. As with any kind of "art", it's subjective and I know that some people will love a certain style that others will either dislike or be neutral about.
I'll respond individually later.
At this point, I'll say that the "unique technique" found in these photos, is simply a device that gets the child (or animal, or actor, or any subject) to give all their expressions directly to the camera lens. The thing that is different about this is that you would never get that many pics of a kid looking directly at the lens w/o such a device. I think (hope?) that parents will see real value in this, as it kind of captures the soul of their kid in a way that a picture of a kid emoting with their eyes away from the lens does not.
