Nice shooting. Aside from the slightly lopped off limbs, the family is posed well and thy seem to be having a good time - which is important!
I just did a family shoot (I put some pics up somewhere down below!) and it is definitely difficult to avoid cropping off limbs and fingers when there is a lot going on! I still noticed that I did it in some of the shots, but I tried to always allow for a lot of extra room around the subjects if I knew it was going to be essentially a full body shot. In most instances that seemed to work - but I was consciously thinking about it the whole time!
