Family photos are so fun to shoot and deliver as I know over time they gain more substance. Looking back 10/20/30 years at a family photo evokes emotions and memories.
Pro tip: Shoot at 1.8 or so by stepping back and isolating the group. Leading lines, right light all part of the set up. Then rotate and shoot again. A good rule of thumb is take the same number of shots as the number of people, so 4 images in each pose for the above group. Unless kids or dogs, then you can never shoot too much.
