Hi Pat,
I agree with Mike in that strangers are frequently less difficult to pose than people whom you know.
I tell people that they're beautiful and this goes a long way toward helping them to relax. I never have to lie about this, by the way: there is always something about a person that slays me. Really beautiful people can reduce me to tears.
I don't like your photo much because I suspect that your daughter in law is a knockout and you haven't photographed her that way. Give her something gorgeous to wear and photograph her at an angle that lenghens her neck and highlights her eyes. Utilize good looking relatives - that's my motto
.
Keep us posted, and best wishes,
Linda
