Feline hit all the main points, right on the head. I found the dangling arm in that last shot to be especially distracting. If you had directed her to put that hand on her husband's arm it would have accomplished two things: It would show that family "connection" to have her touching him in that way, and it would be much more flattering angle for that long, white ARM that hangs down. (This is also why photographers recommend LONG SLEEVES for photos, BTW). A good rule of thumb when it comes to posing people is this: If it bends, bend it. That refers to all bone joints etc. That means that fingers should be gently curved if they are a prominent part of a close up. Elbows don't remain straight out, you bend the arm in some way, by putting hands or thumbs in the jeans pocket, whatever it takes. Start from the neck down, with a slight head tilt perhaps, then shoulders angled, elbows bent, fingers, hips slightly angled away from the camera. If it bends, bend it.
