OK, heres my take....
#1 Sorry, but I think it's spoilt by you cropping the heads off the adults (I assume thats a crop and not done "in camera") I think this shot would have been great if we could have seen them complete)
#2 Now this was getting better, great adult pose, a certain feeling of "togetherness" - but I'm afraid the kids almost spoil the pick with them just "doing their thing". It almost feels like they are there by accident.
#3 Again, getting better but the photo seems a little "disjointed" - I think the parents should make contact with each other - and the position of her feet doesn't make a very flattering pose.
#4 These are both much better! (but maybe each would benefit from a landscape crop rather than portrait)
#5 Sorry, these do nothing for me. The exposure appears off and not sure what their expressions are telling me.
#6 I'm not sure why you are cropping heads off again, but it would be improved if they were left on.
#7 Again, it looks like the adults are having a good time while the kids are left to "get on with it". I think they all need to be involved in the photo - or not be there at all.
Just my thoughts - thanks for sharing.
