Yeah, she certainly looks like she requires high maintenance!!
That was a joke, by the way.
Ah, this is coming from a non professional photographer, but in my line of work people get very very very very very very very very angry when things don't go as planned, so this may or may not be helpful to you.
For me I would just take it as they come. You explained to them how it was going to be, and they were satisfied with that, and therefore they signed a contract, and in essence, an informed consent. You did your job in the best way possible, and provided everything you said you would, both verbally and contractually. If you think that this particular job was done like all other jobs that you have done, then I think you need to move on, and let them deal with their anguish. It could well be that her anguish goes way beyond looking at what she thinks bad pictures. Who knows, they may take legal actions, but I think that kind of things go with the territory, so to speak. If you truly think that your work is satisfactory to you, then you need to stand on them, like a professional photographer (I am not saying that you are not, OK?).
As for your pictures, they are too small for me to comment. Besides, I am no expert anyhow.
My guess is that shooting photo for a living is a tough way of life (probably even for someone like Benjikian!!). Unless you are flooded with requests to shoot numerous weddings, I am not sure if you should be cherry picking them. I am sure that there are much to be learned, if not more to be learned from things that went wrong than otherwise. Learning how to deal with difficult clients will undoubtedly be beneficial to your practice in the end.
Also, and if you are professional, you will not let this affect your performance on the next project. I think that is what this is all about.
So I recommended to look at it that way.
Sorry for preaching here
