I like the last one. It has a sort of lartigue feel to it because of the low perspective.
I like the last one as well because they both have the same expression.
I love the girl's face in the first one, and the last one is great, too.
The last picture is precious and hysterical.
The last one is the best, it seems as though it is a mirror image.
Last one for sure. As ben would say "for cute"
#5 is definitely my favorite--partly because of the dog, but also because of the angle of their heads.
I really like the fifth one. Their expressions are perfect.
I'm drawn the the black and white photo of the whole family. It may not be the popular choice, but I think it has more to it than just the regular family shot. maybe it's their expressions, but only my last look through this post that one caught my attention more than before.
I think the desaturation of the final image really brings out the similarities between the boy and the dog. I think the color might have distracted, and made them feel more separate.
