with the small pictures posted, I can't really tell the focusing issues. In portrait photography, it's crucial that you get the eyes in focus. Now, maybe we'll say you're older fashioned, but many people like this "old-ish look". The only one I see that doesn't have acceptable focus is #10 (where the hair is in focus). She may not suit your style, but she isn't a 'faux-tographer'. that's being a bit harsh.
She has a vision, and a clear style. It may attract your wife, but perhaps not you. And in the end, maybe it isn't her fault if it's her style. Your wife should've discussed it with you. The only thing I find her guilty of (when shooting multiple people) is shooting with such a narrow DOF. 85 f/1.2 II is good for single person shots... even then, you'll have to be PERFECT straight on to get acceptable focus.
But I don't see anything wrong with her shots (again, maybe it's because the small size pics) except for #10, where the focus is on the hair. I don't know her in anyway, but your not talking about her ability to take photographs, but more of her style.
I guess if I was talking with a client before a shoot, I would definitely talk about shots. Have an interview to see what the client is looking for. I'd definitely ask to see if they would have ANY pictures that they admire, and go after that. Photography is very subjective, when you mix art into it. If people want a standard picture, please ask for it.
