I like 1 & 3. The first one catches my eye as a result of the point of focus. I like the way you have chosen not to focus on your brother but instead the toy and the DOF is just right blurring your brother slightly but not so much that you can't make him out. Also I like the shadows in 1 & 3 covering half of his face in both cases. 2 just reminds me of a standard family print.
