On Thurs, for Mother's Day, I'm doing a group studio shot of my nephew & 3 neices. He is a strapping 6 ft+ tall 16 y.o, and the older, 14 y.o. neice is about 5' 5". Then there's the 2 paternal twin girls, which are just 5 y.o. How would you suggest I assemble their pose? I'm also doing individual shots of all of them, so any thoughts on those poses (and anything else related to this subject), would also be appreciated.
