Nice job with a group who didn't read any of the dress instructions.  A couple of pointers:

Watch the shadow on the guy on the right.  I had this problem on a group recently as well.  Bring him more forward or move the light more to the center.  Nice composition however ... watch the woman's elbow too.

Same shadow and a little farther away ...

Then 3/4 but that damn shadow.  Also, don't cut off a hand 1/2 way ... either leave it in entirely or remove it entirely but dont put just 1/2 of it in.  Again her elbow is starting to bother me now.  That had could have been put on her son to our left to both connect them and solve the elbow issue

Now the shadow is solved ... and I think I like the man taller than the woman as a rule.  I think i'd like to see a little more at the bottom ... if it doesn't look bad for her waist.

This one is also nice ... but there will be a focus problem because the faces need to be more in line.  I think that there is too much distance between the gusy on the floor and the man in back ... one or the other will start to go out as we enlarge this pose.  Also, I'm not sure about the cropping at the bottom again.  I think it needs more of the bottom ... with some attention to hand and leg position

Also, the guy on the right at bottom could move about three inches to our right to make it less of a straight line between mom and son.
